1
00:00:00,390 --> 00:00:04,170
I want to implement a daily STREAKS system into my game.

2
00:00:04,170 --> 00:00:08,370
So if a player plays five days in a row, my game will know it.

3
00:00:08,370 --> 00:00:09,510
Something will pop up.

4
00:00:09,510 --> 00:00:14,100
Say congrats, maybe give them a prize, you know, per day or something.

5
00:00:14,100 --> 00:00:18,330
But with that in place, we can also figure out daily rewards.

6
00:00:18,330 --> 00:00:20,880
So we're going to know when there was a day rollover.

7
00:00:20,880 --> 00:00:22,590
You can give him a reward for that.

8
00:00:22,590 --> 00:00:24,330
That's very popular in games.

9
00:00:24,450 --> 00:00:30,420
And finally, with this system in place, we're going to know if it's the first time somebody played.

10
00:00:30,420 --> 00:00:35,430
So then we could use that information to pop up instructions for first time players.

11
00:00:35,430 --> 00:00:37,530
So let's go ahead and get started with that.

12
00:00:38,070 --> 00:00:43,740
Go to server script service and then open up the game manager in server script service.

13
00:00:43,740 --> 00:00:49,140
And we have our function ad board, which is slightly misleading because we do add the board, but we

14
00:00:49,140 --> 00:00:52,650
have other player info that does not go on the board.

15
00:00:52,740 --> 00:00:56,130
We're going to add two more values to that player info.

16
00:00:56,130 --> 00:01:03,240
We're going to say local saved type time equals instance new.

17
00:01:03,270 --> 00:01:12,390
It's going to be a number value and that information is going to go on player info and let's give saved

18
00:01:12,390 --> 00:01:18,120
time a name I'm going to call it saved time.

19
00:01:18,120 --> 00:01:19,230
All one word.

20
00:01:19,590 --> 00:01:23,340
I'm not going to do this space because then I can't use the dot notation.

21
00:01:23,790 --> 00:01:24,020
All right.

22
00:01:24,050 --> 00:01:28,680
I need another variable to I'm going to do one for streak, right?

23
00:01:28,710 --> 00:01:32,070
That's my daily streak instance new.

24
00:01:32,070 --> 00:01:35,460
That's an int value because it's going to be like one, two, three, four.

25
00:01:35,490 --> 00:01:38,160
That's also going to go on the player info.

26
00:01:39,090 --> 00:01:49,170
We will give that name streak, dot name, capital streak.

27
00:01:49,840 --> 00:01:54,050
Let's scroll down to initialize player data.

28
00:01:54,070 --> 00:01:55,430
There it is.

29
00:01:55,450 --> 00:01:58,030
Now we have two situations.

30
00:01:58,030 --> 00:02:01,330
The player might have data and this is an update, right?

31
00:02:01,330 --> 00:02:03,220
So we may have people playing already.

32
00:02:03,220 --> 00:02:04,930
We don't want to reset their data.

33
00:02:04,930 --> 00:02:08,590
We have to take into account for their old data and then we have new people.

34
00:02:08,590 --> 00:02:10,300
That's not going to be a problem.

35
00:02:10,300 --> 00:02:11,740
As soon as they come in.

36
00:02:11,740 --> 00:02:13,720
We can give them two new values.

37
00:02:13,720 --> 00:02:22,210
We can give them the streak which will set the one, and then we have our saved time and then that will

38
00:02:22,210 --> 00:02:28,540
set to OSS time, which is the number of seconds after midnight of January 1st, 1970.

39
00:02:28,540 --> 00:02:29,860
Epoch All right.

40
00:02:29,860 --> 00:02:32,320
But this is going to be a problem.

41
00:02:33,430 --> 00:02:35,200
Let's go ahead and check.

42
00:02:35,500 --> 00:02:38,830
Do they have streak data or don't they have streak data?

43
00:02:38,830 --> 00:02:43,000
Because we're only going to have to initialize that one time if they don't have it.

44
00:02:43,000 --> 00:02:50,300
So I'm going to say, if not data dot streak that's been saved off.

45
00:02:50,300 --> 00:02:57,160
Right, then what I'm going to do is I want to get my player, not the leader stats.

46
00:02:57,160 --> 00:03:05,290
I'm going to do the player info and I'm going to get my street value street value set that equal to

47
00:03:05,290 --> 00:03:06,210
one, right?

48
00:03:06,220 --> 00:03:08,080
Because this is brand new for these people.

49
00:03:08,080 --> 00:03:10,660
They just came in since our patch.

50
00:03:11,080 --> 00:03:17,980
Do a control C do a control V, this is going to be saved time saved time.

51
00:03:17,980 --> 00:03:23,530
That value is also going to be O's dot time.

52
00:03:24,700 --> 00:03:24,970
All right?

53
00:03:24,970 --> 00:03:28,090
And then the next time they come in, they're already going to have that data.

54
00:03:28,090 --> 00:03:29,620
So we don't want to do that.

55
00:03:29,620 --> 00:03:31,360
We're going to do an else.

56
00:03:32,260 --> 00:03:33,820
Let's copy this.

57
00:03:34,210 --> 00:03:36,460
I will put real values there now.

58
00:03:36,460 --> 00:03:36,880
Right.

59
00:03:36,880 --> 00:03:38,500
So now we don't need that one.

60
00:03:38,500 --> 00:03:41,320
We could do a data dot streak.

61
00:03:41,320 --> 00:03:48,310
It's going to be there and we'll do a data dot saved time.

62
00:03:49,540 --> 00:03:50,020
All right.

63
00:03:50,020 --> 00:03:51,100
That's looking good.

64
00:03:52,450 --> 00:03:54,870
We want to check here for our daily streak.

65
00:03:54,880 --> 00:04:01,380
Let's do a check, daily streak and we'll pass in the player.

66
00:04:01,390 --> 00:04:02,860
We don't have that function yet.

67
00:04:02,860 --> 00:04:03,960
I think I'll copy it.

68
00:04:03,970 --> 00:04:07,390
Control C so I don't have to worry about spelling it wrong.

69
00:04:07,390 --> 00:04:11,170
As long as you're above initialized player data, you'll be all right.

70
00:04:11,170 --> 00:04:16,470
I'm going to go below the ad board function, right.

71
00:04:16,540 --> 00:04:18,310
I just want it closer to the top.

72
00:04:18,550 --> 00:04:23,170
Let me do a local function check daily streak.

73
00:04:23,170 --> 00:04:24,700
I just did a paste there.

74
00:04:25,270 --> 00:04:26,860
Let's get a couple variables.

75
00:04:26,860 --> 00:04:31,390
I'll do one for saved time.

76
00:04:31,480 --> 00:04:37,540
We'll go get our player, get the player info from the player, and then we're going to get the saved

77
00:04:37,570 --> 00:04:39,850
time dot value.

78
00:04:40,960 --> 00:04:49,870
I'm going to need the seconds per day and that's 86400 seconds in a day.

79
00:04:51,640 --> 00:04:52,480
What else do I need?

80
00:04:52,480 --> 00:04:56,110
I need a variable for now.

81
00:04:56,110 --> 00:05:00,400
The time now I'm going to use O's time.

82
00:05:00,400 --> 00:05:08,200
That's going to give me the number of seconds passed January 1st, 1970, which is Unix epoch.

83
00:05:08,230 --> 00:05:15,310
It's down to the millisecond, but Lua uses the uses seconds for the unit.

84
00:05:15,760 --> 00:05:24,850
All right, I'm going to do another variable called I'll call this now minus one day, and that's going

85
00:05:24,850 --> 00:05:28,360
to be now minus seconds per day.

86
00:05:28,360 --> 00:05:34,060
So since now as in some sort of second units since 1970.

87
00:05:34,270 --> 00:05:38,770
Subtracting off 86,400 puts us back a day.

88
00:05:39,670 --> 00:05:40,990
I need two more variables.

89
00:05:40,990 --> 00:05:45,310
I need one for the formatted saved time.

90
00:05:45,310 --> 00:05:49,900
Those seconds are great, but it's kind of tough for days and stuff like that.

91
00:05:49,900 --> 00:05:53,200
So let's use OS day to format our time.

92
00:05:53,200 --> 00:05:57,700
We have that little single quote star DT.

93
00:05:57,730 --> 00:06:02,410
That means we're going to make a table with saved data.

94
00:06:02,410 --> 00:06:04,150
So we're passing the second send.

95
00:06:04,150 --> 00:06:11,620
We're going to get back right here a table with things like the year, the day, the month, the hour

96
00:06:11,620 --> 00:06:13,270
is going to be very convenient.

97
00:06:13,480 --> 00:06:15,880
We're going to need another one for R.

98
00:06:15,910 --> 00:06:28,900
We'll call this formatted now minus one day O's date star T for our table.

99
00:06:29,950 --> 00:06:33,040
And we're going to put now minus one day in there.

100
00:06:33,970 --> 00:06:37,360
Now we can make comparisons on days really easy.

101
00:06:37,720 --> 00:06:38,860
Let's do that.

102
00:06:40,000 --> 00:06:41,800
I'm going to do an if statement right here.

103
00:06:41,800 --> 00:06:48,520
I'm going to say if formatted save time dot why day?

104
00:06:48,520 --> 00:06:58,480
So why day is the day of the year between one and 365 on a normal year one and 366 on a leap year.

105
00:06:58,480 --> 00:07:01,270
But that way I don't have to worry about months and stuff like that.

106
00:07:01,270 --> 00:07:04,300
I have a nice consecutive ordering of the days.

107
00:07:04,570 --> 00:07:11,950
I'll say equals equals formatted now minus one day.

108
00:07:12,400 --> 00:07:15,820
Why day then?

109
00:07:16,390 --> 00:07:24,460
Well, if I subtract a day and the last time I logged in is that same day, I'm going to say that's

110
00:07:24,460 --> 00:07:27,490
a good candidate to increase my daily streak.

111
00:07:27,490 --> 00:07:41,830
So if I have my player dot player info dot streak, dot value plus equals one, that should be pretty

112
00:07:41,830 --> 00:07:42,550
good.

113
00:07:42,550 --> 00:07:47,140
We have some more stuff that to check though, but we don't want that to happen.

114
00:07:47,230 --> 00:07:53,070
We're going to call this periodically, so we don't want this to happen more than once during gameplay

115
00:07:53,320 --> 00:07:54,730
for the same day.

116
00:07:54,730 --> 00:08:03,940
So what I'm going to do is I can get my player player info saved time, dot value equals.

117
00:08:03,940 --> 00:08:12,730
Now then when I save that off, this is going to fail because there's no way that now is the same as

118
00:08:12,730 --> 00:08:14,470
now minus one day.

119
00:08:14,470 --> 00:08:17,620
But we have a few more things to check for.

120
00:08:17,620 --> 00:08:26,380
We have our days good, but we also have to make sure that it's not like a year and a day later.

121
00:08:26,380 --> 00:08:27,430
Let's go ahead.

122
00:08:27,430 --> 00:08:29,890
And why did it do random?

123
00:08:29,890 --> 00:08:33,220
Let's do an and get rid of that.

124
00:08:33,220 --> 00:08:34,750
Go to the next line.

125
00:08:35,380 --> 00:08:40,240
I'm going to do another check to make sure that the years are equal.

126
00:08:43,160 --> 00:08:46,250
So we'll do a year here.

127
00:08:47,950 --> 00:08:49,570
And a year here.

128
00:08:49,570 --> 00:08:52,370
What happens on year rollover?

129
00:08:52,390 --> 00:08:55,420
Well, we went back a day.

130
00:08:55,420 --> 00:09:01,600
So it should be like if if it's December 31st, 2021.

131
00:09:01,600 --> 00:09:02,020
Right.

132
00:09:02,020 --> 00:09:06,100
And we're playing January 1st, we're going to subtract a day.

133
00:09:06,100 --> 00:09:12,610
So these should both be 2021, these should both be 365.

134
00:09:12,610 --> 00:09:16,120
I don't think it was a leap year, but that part will be.

135
00:09:16,120 --> 00:09:20,800
OC Let's go ahead and put this then on the same line.

136
00:09:22,600 --> 00:09:25,330
Let's add two more conditions to our F statement.

137
00:09:25,330 --> 00:09:34,780
So the first condition we are one day apart from our save time and our log in time are now time we award

138
00:09:34,780 --> 00:09:39,190
another value to the streak, but we'll do an LCF.

139
00:09:39,190 --> 00:09:47,680
What happens if the now time minus the save time is actually less than seconds per day?

140
00:09:47,710 --> 00:09:51,970
Let's do less than or equal to just to include that last second.

141
00:09:51,970 --> 00:09:53,830
Well, nothing happens, right?

142
00:09:53,890 --> 00:09:56,530
Because what's going to happen we're going to get down here.

143
00:09:56,620 --> 00:09:59,470
The save time is going to be updated to now time.

144
00:09:59,470 --> 00:10:00,490
We're going to be playing.

145
00:10:00,490 --> 00:10:02,410
We're going to call this many times.

146
00:10:02,410 --> 00:10:04,120
Let's just write.

147
00:10:04,930 --> 00:10:06,550
Playing the same day.

148
00:10:06,550 --> 00:10:09,430
Playing the same day.

149
00:10:10,780 --> 00:10:11,580
All right.

150
00:10:11,590 --> 00:10:14,800
If this is if this fails.

151
00:10:14,800 --> 00:10:15,080
Right.

152
00:10:15,100 --> 00:10:16,770
So we're not a day apart.

153
00:10:16,780 --> 00:10:21,400
If this fails, we are not within 24 hours now.

154
00:10:21,400 --> 00:10:22,680
We'll break the streak.

155
00:10:22,690 --> 00:10:32,290
So I'll say else, just grab this instead of adding the one where you're going to set it equal to one.

156
00:10:32,290 --> 00:10:34,080
And that's going to break our streak.

157
00:10:34,090 --> 00:10:36,370
Let's get a print statement in here.

158
00:10:38,260 --> 00:10:49,240
We'll say added to the streak and then I will put the value of the streak, the new value.

159
00:10:50,500 --> 00:10:51,280
Cool.

160
00:10:51,280 --> 00:10:53,740
And then here we're going to break the streak.

161
00:10:53,770 --> 00:10:54,580
Where should we do it?

162
00:10:54,580 --> 00:10:55,120
Underneath.

163
00:10:55,120 --> 00:10:57,970
Yeah, we'll just say broke the streak.

164
00:10:57,970 --> 00:10:59,530
You broke your streak

165
00:11:04,240 --> 00:11:05,620
with an exclamation.

166
00:11:05,620 --> 00:11:06,700
We don't want to miss it.

167
00:11:06,700 --> 00:11:08,230
Lots of exclamations.

168
00:11:08,530 --> 00:11:10,090
All right, so this is the boring one.

169
00:11:10,090 --> 00:11:11,950
This is the one that's going to happen the most.

170
00:11:12,040 --> 00:11:14,320
Let's scroll down a little bit.

171
00:11:15,480 --> 00:11:21,030
And in our save player data.

172
00:11:21,660 --> 00:11:21,890
Right.

173
00:11:22,080 --> 00:11:23,250
We have to update.

174
00:11:23,490 --> 00:11:28,820
We're going to do an update every time we call save player data, which is periodic.

175
00:11:28,830 --> 00:11:31,560
It's in the save loop and when we leave.

176
00:11:31,950 --> 00:11:36,420
Another thing I'm going to do on that save loop, let's just increase this to 10 seconds because I'm

177
00:11:36,420 --> 00:11:41,460
getting a lot of warnings about the buffer getting filled with our save requests.

178
00:11:41,460 --> 00:11:45,330
So every 10 seconds, save player data is going to happen.

179
00:11:45,330 --> 00:11:49,590
We'll do our check daily streak, pass in the player.

180
00:11:50,100 --> 00:11:52,470
Then we'll get our data.

181
00:11:52,470 --> 00:11:57,690
And data has saved time, right?

182
00:11:58,410 --> 00:12:03,600
Player dot player info save time.

183
00:12:03,600 --> 00:12:13,500
And then we have the streak right streak player dot player info streak.

184
00:12:14,130 --> 00:12:18,810
Oh and these are values dot value dot value.

185
00:12:19,770 --> 00:12:21,740
So we're going to put that in our data.

186
00:12:21,780 --> 00:12:23,220
We're going to save it off.

187
00:12:23,430 --> 00:12:24,330
It'll be great.

188
00:12:24,330 --> 00:12:27,180
And then save loop is now 10 seconds.

189
00:12:27,210 --> 00:12:29,790
That's going to call our save player data.

190
00:12:29,820 --> 00:12:31,710
Let's try this for errors.

191
00:12:31,710 --> 00:12:37,110
You're not going to get exactly the same thing because I've tried this a few times off camera, but

192
00:12:37,110 --> 00:12:38,490
check for errors.

193
00:12:38,490 --> 00:12:42,420
I'll go to view output.

194
00:12:43,250 --> 00:12:45,140
And we can go ahead and clear that.

195
00:12:46,230 --> 00:12:47,220
Hit the play.

196
00:12:51,920 --> 00:12:53,070
And we're not getting expand.

197
00:12:53,220 --> 00:12:56,600
Our air's waves starting.

198
00:12:59,130 --> 00:13:01,040
Playing the same day.

199
00:13:01,050 --> 00:13:01,940
Very good.

200
00:13:01,950 --> 00:13:03,330
So we're playing the same day.

201
00:13:03,330 --> 00:13:04,740
We're not getting any errors.

202
00:13:04,740 --> 00:13:08,220
Let's go ahead and do a little dummy test.

203
00:13:08,220 --> 00:13:10,820
This is in no way comprehensive.

204
00:13:10,830 --> 00:13:13,200
You'll have to test this over and over.

205
00:13:13,200 --> 00:13:15,990
And then you're still going to have to really be careful about the year.

206
00:13:15,990 --> 00:13:16,970
Roll over.

207
00:13:16,980 --> 00:13:24,150
Let me go up to let's look at initialized player data and right here.

208
00:13:24,150 --> 00:13:27,180
So we're going to get data because we already saved it off.

209
00:13:27,180 --> 00:13:34,290
Let's subtract our 86400 seconds.

210
00:13:35,070 --> 00:13:35,370
All right?

211
00:13:35,370 --> 00:13:39,390
And that way we should increase by one day.

212
00:13:39,420 --> 00:13:40,680
Let's hit our play.

213
00:13:45,200 --> 00:13:46,370
Added two straight.

214
00:13:46,370 --> 00:13:47,810
So we have two.

215
00:13:48,230 --> 00:13:48,920
Good.

216
00:13:49,810 --> 00:13:52,450
What happens if we.

217
00:13:54,750 --> 00:13:56,320
Do this.

218
00:13:56,340 --> 00:14:00,780
Let's do three times.

219
00:14:02,430 --> 00:14:04,220
Don't forget, we saved off data.

220
00:14:04,230 --> 00:14:04,560
That was.

221
00:14:04,860 --> 00:14:06,810
That was a little bit older.

222
00:14:07,170 --> 00:14:09,420
We should blow our streak here.

223
00:14:12,270 --> 00:14:14,000
You broke your streak.

224
00:14:14,010 --> 00:14:15,000
All right.

225
00:14:15,390 --> 00:14:16,860
That's looking pretty good.

226
00:14:17,100 --> 00:14:19,380
I'm going to try and do it tomorrow.

227
00:14:19,410 --> 00:14:21,480
Log in before I post this video.

228
00:14:21,480 --> 00:14:26,940
I'll do a couple of days just to make sure there's no quirks in it, but I think we're good to go.
