sticking objects

What I'm wanting to do is have this red ball always "stick" to the blue ball when it hits it, as in no matter what angle the blue ball rotates it will rotate around with it and staying the same place when it moves.

I figured it probablys involves trigonometry, but I'm not the best at math.

any help would be great!

This cap should help you out.

(i didn't make it)

cheers, thats perfect.

Don't forget to rotate the red sprite accordingly, if you want it to keep the angle relative to object it's stuck to.

That should be easy enough to do, if you give the red ball a "stuckAngle" variable. When it sticks, set stuckAngle to it current angle, and after that Always -> Set angle to stuckAngle + blueBallSprite.angle

I have an old cap that does what you're saying

drag and drop either box

hold right mouse button to rotate:

coincidentally, I'm in the middle of adding math expressions and array actions to automate this in 's'
