What should I do so that it can work in a rotate angle?

I created a Popup animation using the 'Destination out' Blend mode:

PopupAnimation.c3p

But I want to go a step further and make it work even while different angles, I don't know how to get it to work correctly. I think there should be some kind of math formula to calculate it

I recommend using an invisible "target" helper sprite , and having your mask object move to the target's location.

If you use a helper object, you have many options, like spawning it in a container with the base object, pinning it, or using the move at angle action to position it.

By math, the formula to get a point from a set distance and angle from another point is:

Target.X = Origin.X + (distance/cos(angle))

Target.Y = Origin.Y + (distance/sin(angle))

Although you have to make sure not to divide by 0, and sin and cos can definitely end up as 0 so I'm probably missing something there...

Edit: Brain no worky in the middle of night.

Target.X = cos(angle)*distance+Origin.X

Target.Y = sin(angle)*distance+Origin.Y

I recommend using an invisible "target" helper sprite , and having your mask object move to the target's location.

oosyrag Thank you! I'll try again

but here's another idea to do the masking with distort meshes and it just works with any angle.

R0J0hound This is magic! Really cooooool! It works perfectly!
