I have a 2D 'sprite' airplane flying through a 3d world. It flies through 3d buildings without crashing. In order to make it more realistic I would like it to explode when it Hits a building instead of flying 'through' the buildings. But I don't know how I could detect the crash, is it possible? .

Need some prep work but a simple overlapping rectangles function should work.

Stop confusing me - 2d in a 3d world lol. errmmmm hows that possible??

You cant... create a 3D airplane and use ObjectRayCast

would love to see a video of what you have so far for a 2D sprite in 3D world - bet it will look odd

If you made a flat mesh the shape of your 2D sprite and then used the 2D image as a texture i think it would work

Plane with alpha textures work. But animating it will be another story.

You could load it as an object then and use the 3D collision commands. I'm not sure i understand what the problem with animating it is?

Why not just use the 3d raycast in the direction the plane is going? You can convert the planes 2d co-ords to 3d easily enough.
