Lets say you wanna make a boss without making it small, also known as default size, making it big or tiny, well this idea sparked in my head while typing this! there maybe flaws like this...
---WHAT PLAYERS CAN DO---
use a Box on the Selecting Model chosen, on a corner, to make it big, make your mouse go up to make it big or make it down to make it small, this way it can grow or shrink!
---WHAT MIGHT HAPPEN IN GAMEPLAY---
Either theres a chance the model will stay in model size for its hitbox or that it will get a big or small hitbox depending on the size, and another chance that developers might add in a feature where a big enemy will kill you by stepping on you!
---A FLAW PLAYERS MIGHT DO---
Players might make the Enemy/player models SUPER SMALL that above sized players cant be able to see them!
---WILL THIS BE ADDED IN 2.5?---
Up to Eric and the Team there might be a post by a mod, or admin in this thread.
So yeah! thats all you need to know!
