Realistic Swing, PhyX_Ch3ck Options

[LordZodiarcheBis...]

Description

This script simulates realistic swinging for a ball and chain trap.
I do not recommend to chose negative maxswing-values or values above 90

How to use

Paste the below scripts into an object. (Replace "obj_chain" and "obj_ball") Place the object in your room.
Hold CTRL and rightclick the object. Select "Creation code". Write "maxchains = XX" and "maxswing = XX" (You can put a value on XX)
Optional you can write "dir = XX" to declare a starting angle. Have fun.

create event:

CODE

for(i = 1;i <= maxchains;i+=1)
{
chain[i] = instance_create(x,y+4+i*8,obj_chain)
}
ball = instance_create(x,y+4+i*8,obj_ball)

dir = 0
e = 0
g = 0

step event:

CODE

for(i = 1;i <= maxchains;i+=1)
{
chain[i].x = x+lengthdir_x(4+i*8,-90+dir+i*g)
chain[i].y = y+lengthdir_y(4+i*8,-90+dir+i*g)
}
ball.x = x+lengthdir_x(4+i*8,-90+dir+i*g)
ball.y = y+lengthdir_y(4+i*8,-90+dir+i*g)


e += 1
dir = lengthdir_x(maxswing,e)
g = lengthdir_x(1,e)

I checked this out and it works great Bistian. Good job on this.
Like you asked in irc, I'll use this. I won't replace the ball and chains in the levels I currently have as the ones that are there are designed specifically for those areas. But I will be using this later.

I do want to clarify something for others using this:

You will need 3 objects: (when he referenced the "obj_chain" and "obj_ball")
A control object.
Chain object.
Ball object.
The script in the first post go in the control object, the others you just need as empty place holders for the ball and chain. You may want to add some interactive elements to the ball, but as far as this script itself is concerned, you only need those 3 objects.

Thanks for clearing that up Dark. I shall be using this for my project Bistian, surprisingly I found one script I need here in the forums!
I didn't know you used Game Maker...ah well.
