Hello.
Today I found out a few problems with my game. I tried to make it how the enemy will die with the impact of a bullet. However, the problem is that the target will die with any sort of impact to it. Whether it be the player running into it or a fellow enemy touching it.

Secondly, in the map editor I created 5 enemies, with one action, the problem is that if one enemy dies the rest die too.

Finally, how can I change the entity? For example, when my player goes next to a car and when i hit the enter button, I want the entity of the player to become the entity of the car.
