This is only shown when one or more error occur to signal that the node won’t work properly. attach Point” in NODE ATTRIBUTES.ĮRROR: One or more errors occurred! The node won’t work properly! For more information check “Attach Point” and “Alt. The node wasn’t able to attach the prop to the target asset this usually happens when the attach point doesn’t exist. The ‘Target’ asset you’ve selected exists but does not contain a Sub Scene node.ĮRROR: Cannot attach “…” to attach point “…” of target asset “…”, check its Sub Scene FBX model in Blender and make sure its skeleton (armature) contains the specified attach point (bone)! For example: to attach a gun to your character’s hand you have to make sure your character exists in current game scene.ĮRROR: Target Asset “…” does not contain a Sub Scene (FBX model)!

Make sure the ‘Target’ asset exists in current scene. Make sure you’ve selected an asset in ‘Target’ attribute, usually this is the character you want to attach the prop to.ĮRROR: Target Asset “…” not found in current scene! it might be because the attach point is not a valid one or the object has been correctly attached to the attach point but is now hidden by the model mesh.įor more information check “Attach Point” and “Alt. The attached object is always static or it disappears, why?Ī. – Disable Debug Messages: tick to disable error and warning messages. – Move/Rotate: when you attach a prop to a character it might be slightly off, maybe you attached a gun to a hand and it’s not in the exact position but it is overlapping fingers, to fix this type of problems you can set these values to move and rotate the prop relative to the bone it is attached to. For example for a gun or a sword you might select “Enemy” so that once it is attached to the character it becomes a weapon and collides only with objects in the “Enemy” Collision Group. – Affected Asset: with this dropdown attribute you’ll be able to specify which assets the prop will collide with once it has been attached to the character, you can either select “All”, “None”, “Enemy”, etc. attach point: here you can specify an alternative attach point in case the FBX model you’re using wasn’t rigged with Mixamo or isn’t using the standard bones names used by Mixamo, to discover names you have to check inside the FBX model you’re using, for example by opening it in Blender ( and checking bones under “Armature”, there you’ll find the complete skeleton of the model and the name of each of the bones that are part of it for example the neck bone in Mixamo might be called “mixamorig:Neck”. attach point” attribute as described in next point. Still be able to attach a prop by using the “Alt. – Attach Point: a dropdown list with all of the 65 standard attach points (bones) available in most models rigged with Mixamo ( While this would work for many models, please note that not every model on Mixamo uses the same bone structure and names in such cases you’ll – Target: the target Character object to which the prop will be attached, MUST contain a Sub Scene node (FBX model).

If touched the hat will attach on top of the head of the target model or detach from it if already attached. Here you can see the node attributes and how simple it is to setup it. These are just a few examples of what you can do. You’ll find all of these cases in the demo BBDOC! – when you press a button: use a UI button. – when you tap on it: use an ‘Is Touched’ node. – when it collides with it: use an ‘If collide’ node.

Now you can have the prop to interact with your character in many ways, let’s say for example that there is a gun on the floor, your character will be able to pick it up and hold it in his hand and this can happen in several ways, a few examples: It is very easy to use, just add the node to a prop then select the target character and an attach point, like the right hand for example.

Here is the skeleton of a model rigged in Mixamo with all the bones names as shown in Blender ( HOW TO USE IT? The node is designed to work with FBX models coming from Mixamo or rigged with it ( since it is a very well established and recognized tool to obtain animated characters the node is also able to work with FBX models coming from other sources as long as they’ve been rigged which means they have a skeleton with bones to which objects can be attached. – Readme file with instruction + useful images and links. – Prop Attach Demo.bbdoc: a demo game showing examples of what can be achieved with the AttachToTarget node. – AttachToTarget.bbnode: the node file you can easily drag&drop inside your Buildbox games. And here’s a quick tutorial showing how you can easily use it in your game!
