> Like the title said, how to add speed/difficulty of the game whenever the player reach certain score?
Depends on what your game's speed is based, if on a simple time scale then, if value "PlayerScore" = 100 let's say, then set "System">"Time Scale" to timescale+(how much you want to add to a timescale).
Here is the condition, the character speed will increase every time player's score incremented by 100, like, 200, 300, 400, ....
Of course I can do it if it's only a static condition like
If score = 100, set speed to 1000
But, this one is different
My brain can't think a way to do it
