Is there any way to make an object collide only with objects I want?

[Ol1vver]

Hello,
Is it possible to make an object collide only with the objects I want?
For example:

I want an InvisibleBlock to only collide with players, but nothing else, and another one to collide with everything except players.

Use AlterCollision tiles.

Use AlterCollision tiles.

And how am I supposed to do that? Select all the objects in the entire map? And what about players only collision? smh

You know you would really benefit from looking in the map editor yourself, there is literally a tutorial map AND a help section that answers this question for you.

Use the IObject.GetCollisionFilter() and IObject.SetCollisionFilter(...) respectively as you need. This is advanced topic and you need to know how the Box2D engine works and operate with their categorybits and maskbits. You will also have to analyze which bits you need to change and how based on how you want the collision to be altered. SFD uses a lot of different collision categories for different purposes.

I recommend that you do not alter default collision behavior for any tile unless you have a very good reason to do so.
