in the blueprint of the player create boolean like: isWounded then use a conditional to check: IF isWounded is TRUE and when it’s true you will run the DecreaseAttack function, else do nothing. You will need to check the state of isWounded continually with a timer. The timer needs to be set to run when the actor spawns into the world. The timer is similar to the tick function found in the C++ code. you can display the status effect on a hud using UMG or just print it as text using blueprints.
