on_Area_entered to detect only 1 body

jonSS

Hello, Is there a way to code only 1 object when entering an Area ?

Iam using this code in a 3D area.tcsn

func _on_hitBox_area_entered(area: Area) -> void:
	victim = area.get_owner();
	$snd_hit_Effect.play();
	
	_flash_create();
	print(get_overlapping_areas()); 
	
	#---set--victim----
	victim.state = attacker.hit_st;
	victim.anim.play(attacker.hit_anim);
	victim.pauseTimer = hitPauseTime;
	victim.health -= 10;
	
	#---set--attacker----
	attacker.comboDelay = 1.0;
	attacker.pauseTimer = hitPauseTime;

The function " _on_hitBox_area_entered " returns an array of all the objects that entered the Area. " hitBoxName.get_overlapping_areas() "

I wanted to be able to switch between detecting only 1 body or multiple objects... this way the areaBox would only hit 1 enemy instead of hiting multiple enemies within the areaBox range.

Is there a way to do it ?

print(get_overlapping_areas());

Well if area would detect only one body while multiple bodies are in then it wouldn't function properly. Seems that this is more a matter of game logic than actual collision detection.

How about this, when an enemy is hit for the first time, set some flag in enemy script. When processing hits, skip enemies that have this flag set. An enemy could automatically reset this flag after some time has passed.

I think one way you might consider solving this problem is by making use of the Collision Layers and Collision Masks under the CollisionObject tab. Making good use of those layers can help you decide which things interact/collide/detect each other.

thanks, i think ive got it working Ive had to make a timer on the hitbox, to prevent it from checking collisions on every cycle... The problem is iam going to have to mess with this timer a lot on the player code.

the attack iam making is for when the player grabs the enemy. Like in the final fight game, the Hit only damages that grabbed enemy.

func _physics_process(_delta: float) -> void:
	
	if ( hitTimer >= 0 ):
		hitTimer -= 0.01;
		hitTimer = clamp(hitTimer, 0, 10  );
	pass


func _on_hitBox_area_entered(_area: Area) -> void:
	
	if ( hitTimer <= 0 ):
	
		var a = get_overlapping_areas();
		var b = a[0];
		
		victim = b.get_owner();
		print(b);
		
		#victim = area.get_owner();
		
		$snd_hit_Effect.play();
		_flash_create();
		
		
		
		
		#---set--victim----
		victim.state = attacker.hit_st;
		victim.delay_frame = 0;
		victim.anim.frame = 0;
		victim.anim.play(attacker.hit_anim);
		victim.frameTimer = 1;
		victim.pauseTimer = hitPauseTime;
		victim.health -= 10;
		victim.motion.x = hitFlyX * hitFacing;
		victim.motion.y = hitflyY;
		
		#---set--attacker----
		attacker.comboDelay = 1.0;
		attacker.pauseTimer = hitPauseTime;
		
		hitTimer = 1;
		print(hitTimer);
