How do I add collision between player projectile and enemies?

I’ve managed to get the player to recognise that its collided with the wall, but how do I make it stop

If it’s a tile based game, you can try to move temporarily the player then if it collides with something you don’t move it.

Or you before you move you can check if the corresponding tile (up, down, left, right) has a wall and if yes you don’t move.
