1
00:00:00,630 --> 00:00:06,360
Let's work on the kills and deaths part of our leaderboard, something every first person shooter game

2
00:00:06,360 --> 00:00:06,960
needs.

3
00:00:06,960 --> 00:00:09,630
And I got the test server running with two players.

4
00:00:09,630 --> 00:00:10,680
There's my other player.

5
00:00:10,680 --> 00:00:11,640
I'm going to kill them.

6
00:00:14,970 --> 00:00:18,060
Bam, We got a kit one for kills the other guy.

7
00:00:18,060 --> 00:00:22,680
I got one for deaths and I awarded the player 50 points for the kill.

8
00:00:22,710 --> 00:00:24,290
I thought that would be pretty useful.

9
00:00:24,300 --> 00:00:26,160
Let's go ahead and get started.

10
00:00:26,790 --> 00:00:29,870
We are going to use the creator tag pattern.

11
00:00:29,880 --> 00:00:32,580
It's a popular roadblock programming technique.

12
00:00:32,580 --> 00:00:39,510
Basically, when we damage a character, we place a tag on the humanoid with the attackers info so that

13
00:00:39,510 --> 00:00:46,820
if the character dies soon after you hurt them, the last person to do damage gets credit for the kill.

14
00:00:46,830 --> 00:00:51,030
You can find a lot of the same code in the roadblocks weapons.

15
00:00:51,030 --> 00:00:53,220
Let's go to our pistol.

16
00:00:53,220 --> 00:01:00,470
I have it in the starter pack simple pistol and then open up the damage script.

17
00:01:00,480 --> 00:01:01,590
There we go.

18
00:01:03,420 --> 00:01:03,570
All right.

19
00:01:03,570 --> 00:01:06,600
Let's get down to lines and start defining our functions.

20
00:01:07,050 --> 00:01:11,580
Do a local function tag humanoid.

21
00:01:11,610 --> 00:01:16,260
I'm going to pass in the humanoid of the thing getting hurt and the player doing the hurting.

22
00:01:16,830 --> 00:01:19,440
And then I'm going to make a variable for my creator.

23
00:01:19,440 --> 00:01:20,160
Tag.

24
00:01:20,880 --> 00:01:23,250
Create a tag equals instance.

25
00:01:23,250 --> 00:01:27,670
New object value him.

26
00:01:27,960 --> 00:01:31,080
So the parent is the humanoid that's getting hurt.

27
00:01:32,190 --> 00:01:37,320
Let's go ahead and get our creator tag name and set that to creator.

28
00:01:37,410 --> 00:01:42,960
You should keep this consistent because a lot of roadblocks, weapons already have this implemented

29
00:01:42,960 --> 00:01:44,640
and they're calling it creator.

30
00:01:44,640 --> 00:01:50,640
So you'll be able to use other roadblocks, weapons that have this seamlessly without doing anything

31
00:01:50,640 --> 00:01:51,180
new.

32
00:01:51,450 --> 00:01:58,560
Let's get our creator tag value and have that equal to the player that did the damage.

33
00:01:58,710 --> 00:01:59,090
Right.

34
00:01:59,100 --> 00:02:05,190
And we have that right because we have that right here on shoot that came through with our remote event.

35
00:02:06,590 --> 00:02:07,520
What else do we need?

36
00:02:07,550 --> 00:02:08,720
Let's do the game.

37
00:02:08,720 --> 00:02:10,950
Dot debris service.

38
00:02:10,970 --> 00:02:15,800
Add item creator tag and make it disappear in 2 seconds.

39
00:02:15,800 --> 00:02:19,680
So we have to do something with this in 2 seconds after we tag the person.

40
00:02:19,700 --> 00:02:22,550
They can't just walk around with a tag for like 45 minutes.

41
00:02:22,550 --> 00:02:26,780
Then when they die because they jumped off of something, you get credit.

42
00:02:27,290 --> 00:02:27,590
All right.

43
00:02:27,590 --> 00:02:29,000
Now we're going to do another function.

44
00:02:29,000 --> 00:02:33,760
This is going to be called un tag humanoid.

45
00:02:34,820 --> 00:02:36,030
I'll pass in the humanoid.

46
00:02:36,050 --> 00:02:37,290
I'll just say HUME.

47
00:02:37,310 --> 00:02:38,370
Easier to type.

48
00:02:38,390 --> 00:02:43,640
Now I'm going to do a for loop for I and V in pairs.

49
00:02:44,090 --> 00:02:48,590
HUME Get children.

50
00:02:51,180 --> 00:02:51,900
Do.

51
00:02:51,930 --> 00:02:55,200
We're going to remove all the creator tags.

52
00:02:55,500 --> 00:03:01,350
Every time somebody hits somebody, we're going to take other people's creator tags off so they don't

53
00:03:01,350 --> 00:03:04,690
get credit to just the person who did the kill.

54
00:03:04,710 --> 00:03:15,030
So V is a tag, maybe a tag if there's one on the humanoid when I check though, if a V is a object

55
00:03:15,030 --> 00:03:16,050
of value

56
00:03:19,110 --> 00:03:31,470
and V dot name equals equals o lowercase creator, then v destroy, right?

57
00:03:31,470 --> 00:03:34,980
So get rid of anybody else's so that they don't get credit.

58
00:03:34,980 --> 00:03:38,040
Only you get credit for the kill the last person to touch them.

59
00:03:38,130 --> 00:03:39,600
Then what we're going to do here?

60
00:03:39,630 --> 00:03:42,480
Get this UN tag humanoid.

61
00:03:42,570 --> 00:03:43,590
Copy it.

62
00:03:43,590 --> 00:03:46,440
Right before we do the take damage.

63
00:03:47,630 --> 00:03:47,890
Right.

64
00:03:48,060 --> 00:03:58,440
Check to see if the humanoid exists and tag the humanoid and then tag the humanoid with your tag un.

65
00:03:58,440 --> 00:04:00,000
Tag everybody else's stuff.

66
00:04:00,390 --> 00:04:01,950
Tag your stuff.

67
00:04:03,610 --> 00:04:04,810
Now what?

68
00:04:04,840 --> 00:04:10,480
Well, now what we have to do is get the players died event and start doing stuff with that tagging

69
00:04:10,480 --> 00:04:13,310
system so we can get points and things like that.

70
00:04:13,330 --> 00:04:17,530
Let's go to server script service, open up the game manager.

71
00:04:17,530 --> 00:04:24,190
When a player is added to the game, we add this board that's good in all, but we need to do more than

72
00:04:24,190 --> 00:04:24,670
that.

73
00:04:24,670 --> 00:04:28,720
So I'm going to add this anonymous function, right?

74
00:04:28,720 --> 00:04:29,950
There's no name on it.

75
00:04:29,950 --> 00:04:33,310
It's just called when Player added is fired.

76
00:04:33,550 --> 00:04:39,670
I'm going to add the board pass in the player this time because it's not an automatic connection.

77
00:04:39,970 --> 00:04:45,220
Then I'm going to get the player character added event.

78
00:04:45,280 --> 00:04:49,510
Connect that to another anonymous function.

79
00:04:49,510 --> 00:04:51,430
Character is going to get passed in.

80
00:04:51,430 --> 00:04:58,630
So player added fires when you enter the game, character added fires when your character is added to

81
00:04:58,630 --> 00:04:59,020
the game.

82
00:04:59,020 --> 00:05:05,530
So if you die and you respawn character added is going to fire every single time you're responding,

83
00:05:05,530 --> 00:05:07,990
this only fires when you enter the game.

84
00:05:08,890 --> 00:05:11,290
So what are we going to do?

85
00:05:11,290 --> 00:05:15,160
Let's get our humanoid from the character because now we've got a character, right?

86
00:05:15,160 --> 00:05:16,330
It's Char.

87
00:05:16,600 --> 00:05:21,580
We'll do a wait for child just in case there's a little slow starting up and then we're going to get

88
00:05:21,580 --> 00:05:22,630
our humanoid.

89
00:05:23,290 --> 00:05:27,460
Now, with the humanoid, we can capture the diet event.

90
00:05:27,460 --> 00:05:31,450
We're going to say HUME Dot died.

91
00:05:32,140 --> 00:05:36,400
We're going to connect that to another anonymous function.

92
00:05:36,400 --> 00:05:42,130
Nothing gets passed in there and we'll get, oh, you know what we should do.

93
00:05:42,130 --> 00:05:48,610
I don't know if you noticed this, but you can actually shoot your gun after you die until you respond

94
00:05:48,640 --> 00:05:50,860
as a roadblocks glitch, in my opinion.

95
00:05:50,860 --> 00:05:52,300
But we're going to fix that.

96
00:05:52,300 --> 00:05:53,260
We're going to say.

97
00:05:53,260 --> 00:06:03,760
HUME on equip tools, just in case you're holding anything for that two or 3 seconds until they respond

98
00:06:04,450 --> 00:06:06,580
that way, you can't fire after you're dead.

99
00:06:07,030 --> 00:06:08,950
So we got that taken care of.

100
00:06:08,950 --> 00:06:09,790
What else are we going to do?

101
00:06:09,970 --> 00:06:12,070
We've got to get our tag from the humanoid.

102
00:06:12,280 --> 00:06:12,640
Right.

103
00:06:12,640 --> 00:06:14,290
The whole reason we're here.

104
00:06:14,620 --> 00:06:15,220
Fine.

105
00:06:15,220 --> 00:06:16,600
First child.

106
00:06:17,950 --> 00:06:19,270
Whoops, I always do that.

107
00:06:19,270 --> 00:06:21,850
Lowercase Creator.

108
00:06:21,850 --> 00:06:24,460
So we're going to look for the creator tag on the humanoid.

109
00:06:24,460 --> 00:06:29,950
There should only be one if tag and tag dot value.

110
00:06:29,950 --> 00:06:35,590
So we want to make sure that the tag exists and the tag has the value just in case something weird happened

111
00:06:35,590 --> 00:06:39,160
and we didn't assign the value, say local.

112
00:06:39,160 --> 00:06:42,370
I'm going to call this e player for enemy player.

113
00:06:42,370 --> 00:06:44,020
This is going to be the enemy player's name.

114
00:06:44,020 --> 00:06:45,940
That's the tag value.

115
00:06:45,940 --> 00:06:47,260
So we died.

116
00:06:47,260 --> 00:06:48,820
Someone else shot us.

117
00:06:48,820 --> 00:06:51,400
That is going to be the one who shot us.

118
00:06:51,400 --> 00:06:52,960
We're going to give them credit.

119
00:06:52,960 --> 00:07:03,790
We're going to say e player leader stats dot kills, make sure kills is on your leader stats value plus

120
00:07:03,790 --> 00:07:04,540
equals one.

121
00:07:04,540 --> 00:07:12,340
Take the old value out of one and then let's give them some points to E Player leader stats.

122
00:07:12,340 --> 00:07:13,240
I spell that right.

123
00:07:13,240 --> 00:07:16,630
Leader Stats points.

124
00:07:17,200 --> 00:07:18,340
How many points do we give them?

125
00:07:18,340 --> 00:07:19,570
Let's give them 50.

126
00:07:19,870 --> 00:07:21,100
50 points.

127
00:07:21,100 --> 00:07:23,500
Now, how do you keep track of deaths?

128
00:07:23,500 --> 00:07:26,590
Well, we don't need to be tagged for the death.

129
00:07:26,590 --> 00:07:27,910
We just need to count it.

130
00:07:27,910 --> 00:07:34,270
So underneath this if statement for tagging player.

131
00:07:34,270 --> 00:07:37,780
So not the enemy player but the player who died.

132
00:07:38,410 --> 00:07:40,270
We'll say leader stats.

133
00:07:42,330 --> 00:07:45,040
Dot deaths.

134
00:07:45,900 --> 00:07:49,200
Value plus equals one.

135
00:07:49,200 --> 00:07:49,530
Right.

136
00:07:49,650 --> 00:07:51,960
Make sure these are spelled the same as that.

137
00:07:51,960 --> 00:07:52,920
It's on your leaderboard.

138
00:07:52,920 --> 00:07:55,920
The name of of the metric on your leaderboard.

139
00:07:55,920 --> 00:07:58,290
And we should be good to go.

140
00:07:59,250 --> 00:07:59,490
All right.

141
00:07:59,490 --> 00:08:02,950
We need to test this out and the test server because we need more than one player.

142
00:08:02,970 --> 00:08:05,610
Let's go to where is it view test.

143
00:08:05,610 --> 00:08:06,270
There it is.

144
00:08:06,600 --> 00:08:08,130
And two players.

145
00:08:08,130 --> 00:08:08,970
That's good.

146
00:08:08,970 --> 00:08:10,410
I'm going to hit the start button.

147
00:08:10,410 --> 00:08:11,820
Then I'm going to pause the video.

148
00:08:11,820 --> 00:08:14,160
All this starts up because it takes a long time.

149
00:08:16,380 --> 00:08:16,920
All right.

150
00:08:16,920 --> 00:08:18,450
Our game is starting up.

151
00:08:19,470 --> 00:08:20,820
I'm going to get my pistol.

152
00:08:22,530 --> 00:08:23,520
There's my other guy.

153
00:08:24,680 --> 00:08:27,370
Oh, he's got his invulnerability bubble on.

154
00:08:27,380 --> 00:08:28,430
Hold on.

155
00:08:33,340 --> 00:08:34,390
Cool.

156
00:08:34,630 --> 00:08:39,730
And if you'll notice, if I die, I'm going to go here.

157
00:08:39,730 --> 00:08:45,640
I'm going to reset my character, and now I'm clicking, but I'm not shooting.

158
00:08:45,640 --> 00:08:45,940
Right?

159
00:08:45,940 --> 00:08:47,200
So we fix that problem.

160
00:08:47,200 --> 00:08:51,970
Before we had that problem, you could you could still shoot while you are dying if you're holding the

161
00:08:51,970 --> 00:08:53,350
weapon in your hand.
