You cannot use increment commands, if you want an object to collide you must use the physics commands, or since you are using increment the other would be to use distance collision following these steps:
drag a loop command inside the enemy and create a variable, "distance" inside the enemy itself, and using the "set" command you use the following formula, of course you must first choose the variable to which you will set the values:
math.distance (x1, y1, z1, x2, y2, z2)
in this case the "x1, y1 and z1" should be replaced by player
example: player.x, player.y, player.z
You will do the same with the rest, only that you will put
(x, y, z)
so you remove the "2" from the formula.
finally it should be something like this:
math.distance (player.x, player.y, player.z, x, y, z)
You must rectify that everything is well written. now use the if command in your case you add it inside the enemy, don't forget that it always goes inside a "loop", now you choose the variable "distance" which is the one to compare and put the value "100" in the corresponding box of In such a way that when this value is not being passed, the ball is eliminated using the "remove" inside the "if", A clarification, the less the distance value, the closer the enemy player will have to be to be eliminated. I hope it's served
