The final product?
So I wanna add a lot of shapes you can spawn, to build just about anything that's possible, not just the 5 you're limited to right now. We're talking a full inventory of them. After you're done building, with what could be well above 50 types of objects, you'll be able to choose from a variety of demolition objects: bombs, projectiles, black holes with varying power.
Why am I not doing it right now? Each shape requires me to model between 15-25 models separately. They need to be textured and then I have to do a lot of linking withing the game to implement the working version. The whole process can take up to 1-2 hours if I'm doing a lot of mistakes. A mistake that happens at the beginning requires me to re-do everything after that again.
