Hi there,
I have a Class called PlayerBehavior, and another class called EnemyBehavior.
Inside PlayerBehavior, I have a method called LowerHealth().
How do I call LowerHealth from within EvemyBehavior? I want to make a simple code where if the enemy jumps, the player loses some health.
Thanks in advance!!
To do this, you need to grab the player actor inside EnemyBehavior:
Sup.getActor('Player Actor')then grab the PlayerBehavior attached to that actor:
Sup.getActor('Player Actor').getBehavior(PlayerBehavior)then call the LowerHealth method:
Sup.getActor('Player Actor').getBehavior(PlayerBehavior).LowerHealth();[ note: I just broke down each part of the code, normally you would just type the one line:
Sup.getActor('Player Actor').getBehavior(PlayerBehavior).LowerHealth();in order to get the desired method ]
Inside my PlayerBehavior class I have:
class PlayerBehavior extends Sup.Behavior {
public playerCol = this.actor.arcadeBody2D;
speed = 0.3;
jumpSpeed = 0.45;
public health = 100;From inside EnemyBehavior, I want to check colission with just the player and lower his health.
For this I have:
if(Sup.ArcadePhysics2D.collides(this.actor.arcadeBody2D, Sup.getActor("Player").getBehavior(PlayerBehavior).playerCol))
{
Sup.getActor("Player").getBehavior(PlayerBehavior).LowerHealth(1);
}However, the screen goes dark when I try this. What am I doing wrong?
Kind regards.
While I'm not quite sure why the screen is going dark, I can offer a different way to go about this.
In your EnemyBehavior, change the collision check to:
if(Sup.ArcadePhysics2D.collides(this.actor.arcadeBody2D, Sup.getActor("Player").arcadeBody2D)
{
Sup.getActor("Player").getBehavior(PlayerBehavior).LowerHealth(1);
}You can then remove
public playerCol = this.actor.arcadeBody2D;
from your PlayerBehavior.
In the future, you can usually just call whatever component you need [ arcadeBody, camera, spriteRenderer, etc. ] directly with:
Sup.getActor('Name Of Actor').NameOfComponentHope this helps!
Thank you once again Spencer. With your help, I was able to finish my quick test with Superpowers. Awesome!
However, I exported the project, and opening the index.html shows a "Could not load plugin list" error. A quick google search showed that it should run if uploaded to a server, so I did. Unfortunately I get the same results. This is the link.
Any reason why that could be happening? Thanks in advance, you've been of great help and I really appreciate you taking the time to reply to my questions :)
