goal : I want the screen to turn red with full screen pass renderer as the player does a 180. The screen effect(it turning red) percent will be connected as the player turns around so it wont be at 100% unless the player has done a full 180, this is why im using dot product. There is no certain trigger and this will happen when i press play. I would like the ditherspead float to change according to the player turning and dither spread starting at 0 and hiting x when the player does a full 180.
Im not the best at coding, but I tried to go as far as I could, here Ill leave the script so far. any help would be appreciated.
