How I can create instance in plugin?

Hello, I try create a behavior "Weapon".

Now I can't create a Instance of bullet in my plugin.

My actions:

1. Create a bullet on project.

2. Create a "tank" with weapon.

3. Add my behavior "Weapon" to the "tank".

4. On the "space" key down I make a shoot from weapon by bullet from step 1.

But for it I must create a new bullet from my behavior script. I saw in Events sheet, that my "tank" as Sprite can use Spawn function for create new Instance Bullet. From script it looks terrible in my performance:

this.type.objtype.plugin.acts.Spawn.call(
    this.type.objtype.instances[0], 
    this.runtime.types_by_index[2],
    this.runtime.getLayerByNumber(this.bullet_layer),
    1
);

Not sure exactly what you want to do, but in general the plugs dont create objects, they only act as conditions, or triggers to make that process easier.

Don't try to call Sprite's Spawn action! That won't work. Look at what Sprite's spawn method actually does - it calls

this.runtime.createInstance(obj, layer, x, y);

Thank's! I do it! :) Now I have a weapon on any created object by behavior... But now I need to finish the behavior. Thank you for help!

in case you can simplify things, here's what I got:

var plugin = this.type.objtype.instances[0];
var image_point = {
    x: plugin.getImagePoint(this.bullet_point, true),
    y: plugin.getImagePoint(this.bullet_point, false)
}
var new_bullet_inst = this.runtime.createInstance(
    this.runtime.types_by_index[2], 
    this.runtime.getLayerByNumber(this.bullet_layer), 
    image_point.x, 
    image_point.y
);
new_bullet_inst.angle = this.angle;
new_bullet_inst.set_bbox_changed();
