This is the editor for actually using my portal game. This is basically like Hammer for source engine. You can't load or save stuff yet. the pause menu is kind of broken look in the options menu for controls. you can't place two objects or textures in the same place, but you can offset them to get more detail and stuff.
I am wondering if I should use vertex math. basically if I do that, I know how to make the game highly optimized to possibly run on lower end devices, but it would take forever. however, if I choose to do the more complicated way, the game will literally take forever to get finished and stuff. I think I will do both, so like the clone collision would be the first portal editor which would be done first, and if I still want to I will also make the math collision version, which would most likely have more features and stuff.
