Get variable from instanced scene to instanced scene?

newMorningKingdoM

Hi, i have enemies and bullets scenes that got instance at main scene and meet there.

Bullets hit the enemies and reduce the enemy health. im using area and group for that. Like

For bullet script: Func area body entered(body): İf body.is in group("enemy"): body.health -= 10

This works. But i dont wanna use collision shapes and areas anymore for bullets. Only raycast for detection because of optimization. i mean there are a lot of bullets and it cause a FPS drop.

but i just can't reach the enemys health variable from bullet script. Both of them are instanced scenes and i got little confused.

Not it's not to the point of bullet hell. So im not intent to use pooling for bullets.

Doesn't RayCast/RayCast2D have a get_collider() method?

You can use this to grab the object the bullet is 'hitting' and simply call the health variable from there. Something like this, I suspect:

var collider : Object = get_collider()
if collider != null and collider is preload("res://path_to_your_enemy.gd"):
    collider.health -= 10

Yes, raycasts give you the collider.

First of all, I know it's not what you asked but I guarantee you you'll save time down the road if you stick to using getters and setters for your important variables like health. I'd change body.health -= 10 to body.adjustHealth(-10). Then keep your adjustment checks in adjust, then finally body.setHealth(health). This will make sure you always know how that health variable is getting adjusted.

With the raycast's get_collider() function you could set up signal I suppose... but probably the easiest way is to send up the object hit though the scene tree. I'd get the parent (maybe the gun) and tell it what it hit. After all I assume it's the gun that knows its damage?

I did a video on how to nodes can share info here: https://godotforums.org/discussion/27714/four-ways-to-share-data-between-nodes Hope it helps
