i want to make a replay system for an rts game
game use bullet behavior for all movement
i can not record every unit x and y and then replay it becuase there is diffrent type of units and the will create in realtime
so i have to save only user input and then do the exact same things
i did that but when i replay the game in diffrent framerate or diffrent timescale , the replay changes and its not exact same thing
so how can i do that ?
