why only chrome? I use only Opera & Firefox...

nice idea! ok, and how do you want to save pictures? svg?

In my opinion that is a microbug of C2...

I need destroy some object when destroying my...

I use next code for it:

behinstProto.onDestroy = function() {
    if (this.destroyObject) {
        this.runtime.DestroyInstance(this.destroyObject);
    }
};

runtimeProto.DestroyInstance = function (inst)
     {
          // Add to death row to destroy later
          this.deathRow.add(inst);
     };

runtimeProto.ClearDeathRow = function ()
     {
                .....
          var arr = this.deathRow.valuesRef();     // get array of items from set

          for (i = 0, leni = arr.length; i < leni; i++)
          {
                        ...

               // Remove from all behavior-plugin's instances
               if (inst.behavior_insts)
               {
                    for (j = 0, lenj = inst.behavior_insts.length; j < lenj; j++)
                    {
                         binst = inst.behavior_insts[j];
                         
                         if (binst.onDestroy)
                              binst.onDestroy();   ///// THIS!!!!!!!!!!
                              
                         binst.behavior.my_instances.remove(inst);
                    }
               }

                        ...

               if (inst.onDestroy)
                    inst.onDestroy();  /// OR THIS!!!!!!
                    
               this.objectcount--;
             }
                ...

if (!this.deathRow.isEmpty())
               this.redraw = true;

          this.deathRow.clear(); // THIS!!!!!!
     };

Some hint you can read in Construct 2, when click on property "Drift recover", read in bottom left corner short description of selected property.

try to use this plugin

or see it as example...

Oops, I did not s?? that this plugin has already made ??himself and exactly the same and called it "Spaceship" too! I based my behavior on behavior "car". Plugin by Fimbul better than mine, in my opinion, although it has bugs in response to "On solid collision"

Kyatric: thanks, many interesting information!

I thought that construct2 does not work with .capx files...

One Way Door - it's cool idea! this is a more abstract concept

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();

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
);
