Hello

I have a problem, I am trying to create a simple SMG type of gun. Using a Line Trace by Channel, I managed to hit a player and cast it to a MyCharacter. If the cast works, then I spawn aExplosion emitter, just to see visually if I am hitting the player. Then i use a Apply Damage Node.

The blueprint for the first paragraph.

Then, I do the following to apply the damage to a player. It checks if the current value is 0, if it is not, then it can apply the damage and change the Health variable I have created.
Blueprint.

When I test this, it behaves wrong. For example, if I use the second player. And I hit the first dude. Nothing happens, the explosion happens, but the damage ain’t applied.

But if I use the first dude, then it does the damage to itself!

Please, let me know how I can do this correctly! Thanks!

Update, Changing the Damaged Actor will now apply from player 1 to player 2. But not from player 2 to player 1.

I got it working. Note! This might not be cheat proof.

The problem is that ApplyDamage works/runs only on the server. So I made a function the following changes.
The client tells the server he hit a player!

The custom function replicates to Run on a server.

Then, the apply damage manages the hitting stuff
