What is the difference between query collision and physic collision?

I’ve just started to learn Unreal development and I’m developing an Atari Pong clone.

I’m having a lot of problems with collision because I don’t understand the difference between query collision and physic collision.

I my ball’s object type is Projectile I have checked the following:

The second column is the Collision Response for the Object Type Projectile.

I confuse because I think Query only is used to overlaps not to block.

What is the difference between query collision and physic collision?

These kinds of questions raise little interest here.

I found the answer in the book “Game Development Projects With Unreal Engine: Learn to Build Your First Games and Bring Your Ideas to Life Using UE4 and C ++”. And the answer is:


Physics Collision is related to physics simulation.

Query Collision is related to collision events and whether objects will bock each other’s movement.
