Circle Movement?

Hey all, do you have a good idea how to make a circle movement using sine or something else?

Here's a way:

circularMovement.capx (r99)

You can do a math.

How to do:

create instance radians = 0;

create instance degrees= 0;

create instance radius = 100; // random radius

initial.x = 50; // random primary x position

initial.y = 50; // random primary y position

Every Thick

degrees = degrees + 5; // each time degrees is increased by 5 degrees

radians = degrees * Math.PI/ 180;

sprite.y = initial.y + Math.sin(radians) * radius // because sin A = y/r

sprite.x = initial.x + Math.cos(radians) * radius // because cos A = x/r

Hey Nimtrix and TELLES0808 Thanks for helping me :D!

What about circle movement with pathfinding?

What about circle movement with pathfinding?

Farsight Use animation to make fake circle animation, you wouldn't alternate the pathfinding movement using sine behavior

i already find another way without pathfinding) i create big circle sprite, its invisible on start and have spin behavior. And when unit appears its pin to circle <img src="smileys/smiley1.gif" border="0" align="middle" />

I've been struggling to get this circular movement right, and finally your solution worked best for me..Thanks a lot.

Thank you Nimtrix...

And please explain me to rotate the same object in reverse order... which you provided in the sample..

— - try subtracting dt rather adding dt to t.

Just change the sin and cos around.
