A sprite passing through a 3D object.

I have a glass object that I created with a 3D object and a weapon that I created using sprites. When the game starts, the gun is pinned to the player's right arm. My player is in the form of a stickman, and each of his parts is separately. I have assembled all the parts into a family and added physics behavior. When the player touches the glass object, the glass cannot pass through it, which is solid. Until this part, there is no problem. My problem is that the gun can pass through the glass. I added solid and physical behaviors to the weapon, but it didn't work. Can anyone help me in this regard?

Sorry for my English, I'm using yandex translation. :D

Moved to the How do I section.

For reference pelinhanci questions like these are better off in the How do I section rather than Construct Creations - the latter is more for showing off what you've created rather than asking for help.

You might want to take a look at our Using 3D in Construct tutorial as it talks more about how the 3D features work, including collisions. The 3D features are still essentially 2D underneath, as explained in that tutorial.
