In this chapter, we’ll continue to implement the procedural game weapon generator in Blender Python. Picking up where we left off in Chapter 2 , we'll start at the top of the grip, continuing forward along −X to build the frame and upward along Z to form the back of the slide with ribbed detail, at which point we’ll have completed the first part of the gun. After that, we’ll create a new mesh object to organize the number of barrel meshes requested by the user, which are automatically resized by the generator to fit the frame and the back of the slide. Last but not least, we’ll add a third mesh object to house the trigger and generate the finger pull through the clever use of a partial parabolic curve.
