How to attach a entity to a bone of a model

[Connor_Briggs]

I am trying to attach a gun to my ai enemies but I just can’t figure it out. I have looked at a bunch of other forums but I just can’t get it to work.

Hi @Connor_Briggs,

Here is a helpful post on how to debug your issue:

[SOLVED] Can't able to attach particle effect to bone

Hey! I am trying to attach the particle effect but having an issue in attaching it. The particle effect gets attached to the entity instead of attaching to the bones and as a result it remains on the same place when animations starts. I used following way to attach particle effect to bone: Here is my public project: https://playcanvas.com/editor/scene/941959 Note: Use T for attack

You can also use the new Import Hierarchy option when importing your NPC model. That way you will get the full bones hierarchy and you can easily drag and drop an entity as a child there. That way you can do the same thing without code.

i don’t see that setting in the editor

[Connor_Briggs]

can you do that to my npc model plz

[Leonidas]

@Connor_Briggs

i don’t see that setting in the editor

You can find it here, under your project settings:

thanks i’ll try that

[Connor_Briggs]

can some body make a simple code with the M-16 model attach to the right-hand bone and make it work with animation

@Leonidas

You can find it here, under your project settings

You have to enable the Convert to GLB option first to be able to see the Import Hierarchy option.

If you enabled both options and upload your character again, you can see all of the character’s entities in your hierarchy and add another entity to it.

var box = new pc.Entity('cube');
    box.addComponent('model', {
    type: 'box'
});

box.setLocalScale(30, 30, 30);
pc.app.root.findByName('MaleBaseMesh:Hips').addChild(box);

i am trying to use this code because it works on the animation and doesn’t lag as badly.
problem is it will load if it is a cube but not any of my gun models

[Connor_Briggs]

I tried the import option and it just crashed again and again

[Connor_Briggs]

i tried to change the code above it to my gun models and it said it is already parented and when i reparented it,it wouldn’t load the model at all

[Albertos]

Did you already tried something like below (based on your current project)?

this.gun.reparent(this.app.root.findByName('mixamorig:RightHand'));

[Connor_Briggs]

no sir i haven’t yet

[Connor_Briggs]

it just says reparent undefinded

[Albertos]

@Albertos

this.gun.reparent(this.app.root.findByName('mixamorig:RightHand'));

Probably because the capital letter.

this.Gun.reparent(this.app.root.findByName('mixamorig:RightHand'));

[Connor_Briggs]

oops

[Connor_Briggs]

well no errors but the model isn’t there

[Albertos]

That’s good so far. Try to use the solution from the topic below.

[SOLVED] Entity disappears with reparent

I have some problems with setting the weapon-output in front of the weapon. First i try to do it with reparent the weapon-output to the weapon (and after that i want to set an offset to the front of the weapon). But if i use this.weaponOutput.reparent(this.weapon) the weapon-output disappears. Can someone tell me why this happens? I create a sample project so you can see the problem. https://playcanvas.com/editor/scene/867937

I guess ‘weapon’ in that topic should be your character and ‘weaponOutput’ should be your gun.

[Connor_Briggs]

thanks for the help i’l take a look at the topic below.
If i can’t get it to work i’t talk later (about to leave for sccocer pratice)

[Albertos]

I will try it myself tomorrow using the full hierarchy, because I think this is much easier for setting the correct scale and rotation.
