How to make NPC's use abilities?

Asked by

5 years ago

I'm working on an open-world game where players can go around and kill NPCs. I know how to make regular NPC's that can attack and follow, but I don't know how to make ones that can use abilities. If it helps, here are is an example of what I mean along with the script and the ability I want the NPC to use.

Example (Source: Boku No Roblox): https://gyazo.com/d48f069d1305394bff66a70f7c81cff8

The ability I want the NPC to use (keep in mind that I'm not good at making particles): https://gyazo.com/b65e08d3eb7100bf27efaf02ed05dd7d

Script: https://pastebin.com/00Z9jRvn

you can use magnitude to see how close two characters are from each other (NPC.Torso.Position - YourCharacter.Torso.Position).Magnitude royaltoe 5144 — 5y

If the two characters are close in distance have the npc attack the character royaltoe 5144 — 5y

You can then let the npc use the attack on the character if the character is close enough to the character. royaltoe 5144 — 5y

Thanks! Also, would that be local script or script? hihowareya115 53 — 5y

Also, if you don't mind, i'm still new to scripting (2-3 months of experience), could you go into detail? hihowareya115 53 — 5y

Sure, do you want to talk on discord? Lucy#0003 royaltoe 5144 — 5y

We worked it out on discord. Here's the code if anyone wants to try it out for themselves: I tried to add comments to explain, but comment if you have any more questions.

01local effects = game.ReplicatedStorage.Effects
02local NPC = script.Parent
03 
04function useFireball(playerToAttack)
05    --create the fireball
06    local fireBall = effects.MagicSkill:Clone()
07    fireBall.Position = NPC["Right Arm"].Position
08    fireBall.Parent = workspace
09 
10    --weld the fireball to the npc's hand and destroy it after .1 seconds to give the effect that it came from the npc's hand. 
11    local weld = Instance.new("WeldConstraint", fireBall)
12    weld.Part0 = fireBall
13    weld.Part1 = NPC.RightArm
14    wait(0.1)
15    weld:Destroy()
16 
17 
18    --give the fireball a velocity.
19    --shooting at the direction of the player's head
20    local velocity = Instance.new("BodyVelocity", fireBall)
21    velocity.Velocity = CFrame.new(fireBall.Position, playerToAttack.Character.Head.Position).LookVector * 100
22 
23    --create an event that explodes the fireball when it touches a character
24    fireBall.Touched:Connect(function(hit)
25        local explosion = effects.Explosion:Clone()
26 
27        if hit:IsDescendantOf(NPC)or hit:FindFirstChild("ParticleEmitter") then return end
28 
29        explosion.Position = fireBall.Position
30        fireBall:Destroy()
31        explosion.Parent = workspace
32 
33        if hit.Parent:FindFirstChild("Humanoid") then
34            hit.Parent:FindFirstChild("Humanoid"):TakeDamage(30)
35        end
36 
37        wait(5)
38        explosion:Destroy() 
39    end)
40end
41 
42while true do
43    wait()
44    --every 1/30th of a second,
45    --loop through the list of players in game
46    for i, player in pairs(game.Players:GetChildren())do
47        --if that player has a character...
48        if player.Character then
49            --get the character's distance from the npc
50            local distanceFromNPC = (NPC.Torso.Position - player.Character.UpperTorso.Position).Magnitude
51 
52            --if the player is 100 studs or closer to the npc
53            if distanceFromNPC <= 100 then
54                --have the npc attack the player with a fireball
55                useFireball(player)
56                wait(5)
57            end
58        end
59    end
