Bullet hell help

Help and Feedback Scripting Support
#1

I made a script for a bullet hell attack in a game im making, and this happens instead, I want to make them move gradually and disappear.

If you need more details ask in replies.
Sorry for bad code, I’m still newbie at coding.

	local rs = game:GetService("RunService")
	for j = 0,1000,1 do
		wait(0.01)
		local clone = attacks.bullethell.bullethellbullet:Clone()
		clone.Parent = attacks.bullethell
		clone.Position = Vector3.new(0,99,0)
		rs.Heartbeat:Connect(function(delta_time)
			clone.CFrame = CFrame.new(clone.CFrame.Position) * CFrame.fromOrientation(math.rad(0),math.rad(math.random(0,360)),math.rad(0))
			clone.CFrame = CFrame.new(clone.CFrame.Position + clone.CFrame.LookVector * 55 * delta_time)
		end)
		print("done")
	end

I took the cframe part from dancing line code.

I’m guessing the end of the video is the part you are referring to?
Are they supposed to be like bullet streaks?
Is their orientation off?
To make them disappear you need to lerp or animate the Transparency from 0 to 1.

#3

yes,

its supposed to go out of the center bar, and go forward in a random direction,

how do i turn that on or off?

#4

I would define start and end positions for each clone. Then I would set the size of the clone to a small number and calculate the distance between starting and ending positions. Then I would tween the size and cframe to animate the part. You need the distance for the final size. You need the average between start and end positions for the final position. The start and end orientation would be lookVector = end-start, upVector = Vector3.yAxis.

#5

I found a little bit of a fix but since the math random happens for every server heartbeat the bullet parts just end up around town.

	for j = 0,10,1 do
		wait(0.01)
		local clone = attacks.bullethell.bullethellbullet:Clone()
		clone.Parent = attacks.bullethell
		clone.Position = Vector3.new(0,99,0)
		rs.Heartbeat:Connect(function(delta_time)
			clone.CFrame = CFrame.new(clone.CFrame.Position + clone.CFrame.LookVector * 55 * delta_time)
			clone.CFrame = CFrame.new(clone.CFrame.Position) * CFrame.fromOrientation(math.rad(0),math.rad(math.random(0,360)),math.rad(-90))
		end)
		print("done")
	end

just incase you got the wrong idea

#6 
local rs = game:GetService("RunService")

for j = 1, 1000 do
    task.wait(0.01)
    local clone = attacks.bullethell.bullethellbullet:Clone()
    clone.Parent = attacks.bullethell
    clone.CFrame = CFrame.new(0, 99, 0) * CFrame.Angles(0, math.rad(math.random(0, 360)), 0)

    task.spawn(function()
        local conn
        conn = rs.Stepped:Connect(function(_, dt)
            if not clone.Parent then conn:Disconnect() return end
            clone.CFrame = clone.CFrame * CFrame.new(0, 0, -55 * dt)
            if clone.Position.Magnitude > 500 then clone:Destroy() conn:Disconnect() end
        end)
    end)
end

Untested … I hardly ever use heartbeat, no need to test anything that fast, 500+ times per second don’t have many real uses.

#7

wait is the spawn task the same as in geometry dash?? (runs a block of code, or triggers in geometry dash terms)

#8

it works but wrong orientation, not ur fault btw, thank you soooo muchh <3

#9

task.spawn(function() puts the bullet on it’s own task and cleans up after itself generically. This way you can shoot more than once using the same function. Stepped is keeping everything moving by the FPS. This is as fast as you would be able to see it anyways and not as taxing as Heartbeat.

#10

You can do this regardless of task.spawn
Actually your code would work the same if you removed task.spawn
This is because connecting a function to a frame event doesn’t yield the current thread.

task.wait() will yield Heartbeat.
Advanced understanding of frames and task scheduling can be found here

See task for functions concerning the timing of your code.
task.spawn will run the function immediately and will resume the script as soon as the function yields or finishes. task.defer will run when the script yields or finishes.

#11

Not as well… This is also good memory management being self-clearing.
Notice how this went from 10 to 1000.

That’s a bit redundant don’t you think. Stepped flawlessly stays with the FPS.
task.wait() Heartbeat has no chance of being in sync.

You’re a bit off here…
task.spawn will run the function immediately and will resume the script immediately.
task.defer will always wait until the current execution finishes or yields before running the function.
