How do I make an actor float.

iDeveloperz

Sorry for being a bit vague but how would I make say a button float so it is always moving in the same spot.

Like a fish in a water.

I saw something in the wiki about this... can't remember where but it's there... moving in a wave motion... could tweak that a bit

Thanks man Ill have a look now.

Is it a tutorial or a how to?

Nah I can't seem to find it.

Has anybody else here done this before?

to make an actor float you can do:

constrain attribute : self X to sin( self.Time * "speed" ) * pixels to move + starting positionX

speed - any integer
pixels to move - any integer - for example if you put 30 the actor will go 30 to the right and 30 to the left , so the total movement will be 60 pixels wide.
starting positionX - the initial X value of the actor in the scene (do not use self.x)

this will make the actor to move left and right !

if you want to add a little up and down to imitate float do this for the Y :

constrain self.Y to sin( self.Position.X * speed)*pixels to move+ starting position Y

here instead of using self.time we use self.x because self.time will make the actor go in an angle .
i suggest to put a small number in speed here to make a float

hope it helps

Thank you very much p-o-m it worked!
