Hello All!
I am recreating “Doom” on Playcanvas, and I’m looking to add a gun fire effect true to the original version.
I have created a script that is supposed to enable a sprite in front of the player’s gun, but it gives me an error. Does anyone have any idea of what’s wrong, and what I should do to get this to function?
@RumaiIndustries It looks like from the screen shots that the sprite you are trying to enable is a child of the camera entity of which the script it is attached to and not a attribute of the this.entity itself. I don’t know if this will help you or not but you could have a look at how I did this here:
Instead of attributes you can also use findByName. With this you can find and enable a child entity or another entity in your scene.
this.entity.findByName('Name').enabled = true;
this.app.root.findByName('Name').enabled = true;

Thank you so much, both of you!
@Albertos, this worked well, is there a way to wait a second and then disable it again?
Thank you in advance!
I think it should be something like below.
var Example = pc.createScript('example');
// initialize code called once per entity
Example.prototype.initialize = function() {
this.sprite = this.entity.findByName('Name');
//this.sprite = this.app.root.findByName('Name');
this.timer = 0;
this.timerActive = false;
};
// update code called every frame
Example.prototype.update = function(dt) {
if (this.app.mouse.isPressed(pc.MOUSEBUTTON_LEFT)) {
this.timerActive = true;
}
if (this.timerActive) {
this.timer += dt;
this.sprite.enabled = true;
if (this.timer > 1) {
this.timer = 0;
this.timerActive = false;
this.sprite.enabled = false;
}
}
};
That was so simple, I can’t believe I didn’t think of that.
Thank you so much @Albertos, It worked perfectly!
