My enemy has five states (IDLE, CHASE, GRAB, EXCUTION, DEATH). When Player enter enemy's "Player Detection Area2D", enemy will move its state to CHASE. Once Player collided with enemy, enemy will move its state to GRAB. During the GRAB state, player can escape from enemy by mashing the button. If one is already in GRAB state, others wont be in GRAB state by emitting a signal and disabling "Player Detection Area2D". As Area Exited Function will be called and those who are not in GRAB state will return to IDLE state. The problem occurs when various enemies collided with Player at the exact same time and one is returned to IDLE state. The button mashing bar still shows up upon the enemy of IDLE state, even though it is not in GRAB state. I tried to solve this problem with a line of code if enemy_state != state.IDLE and enemy_state != state.CHASE: emit_signal("button_mashing") inside GRAB state. However, the button mashing bar still shows up. Do you have any idea to fix this problem?
