Hi Happymug, i've just bought your asset from yoyo, looks promising, but once I start debuging and playtesting, looks like there is no collision and everything falls through the solid ground. I tried enabling "solid" on all relevant objects, as well as enabling physics but the results are still the same :) started looking through your code how do you control gravity and collissions, and do you use GMS built-in physics and col, or custom?
