How do I have an object return to it's original height?

I want an object to dive down, hit something, then return to it's original height before doing it again.

I was originally having it do this by drawing a long thing sprite when it started diving and then having it colide with that off a bounce, but that was making it get lower and lower with each subequent dive because of the thickness of the sprite.

So now I'm trying this with having a variable set itself at the objects y position when it starts the dive, and then checking when it hits a y postion equal to the variable to stop it, but it's not doing anything and I'm not sure why?

Probably because the Y co-ord can be to many decimal places so it's struggling to get an exact match. Try using floor(sprite.y) to round to a whole number or use the good old less than or equal to sprite.Y.

If you're using Set Size, then this is likely due to the way relative scaling works in C2 (and I guess C3). The most direct way is to store your height in an instance variable, which is initialised at layout load. That way you always have a value reference with which you can use 'Set Scale' which is more reliable.

I think by "height" he meant "distance" - after bouncing off solids the object should travel the same distance back.

Less than or equal too worked perfectly, cheers Plinkie.

Yeah sorry faulknermano I wasn't clear enough, by height I meant it's y position on the map, not the height of the actual object.
