Actor with projectile movement sometimes doesn't collide

Hello,

First of all, i’m using 2d paper.

Let’s say i have a gun that can shot (Projectile Movement) a BULLET (Actor), and when that BULLET hit (Collision) something (Second Actor), it will disappear (Destroy Actor).

In my case, when my Bullet hit something, it sometimes collide and destroy itself, but sometimes it does not, when this bullet does not collide to destroy itself (It should collides but i don’t know why it doesn’t work), then this Bullet will go pass through the Second Actor (Let’s say an enemy or a wall) like nothing happened.

Does this happens to you or it’s just me? Sometimes i think it’s because of the low fps when i’m testing the game (Play mode) and sometimes i think it’s because of the projectile movement that doesn’t work well, correct me if i’m wrong. Or does anyone has a solution for this?

Thanks for the answer.
