air will be blown over your body either way, all you're changing is the direction the air is coming from. blowing from the ceiling means blowing hotter risen air
would be nice with a test for a sealed fan like I described. the problem with that setup is that the negative pressure will try to pull from both windows, competing with the fan trying to blow out and not getting as much flow
it's the same reason a breezy summer day feels cooler, the air is still cooler than your body temp and draws away heat better than sitting in still air, plus its more evaporation if you're sweating hot. also indoors without AC during summer is an insulated oven.
If AC isnt an option, the way Ive gotten through summers without is opening one window on one side of the building, then another one on the opposite side. Then point a box fan facing outward of one window, and do your best to seal the gaps with some cardboard or whatever you have. This will create negative pressure in the building, drawing in a bunch of air from the opposite window.
You can do a lot without knowing a lot going with unreal(game engine), mixamo(character animations), and whatever free models you can find. Unreal has some starter projects, a small 3D arena with a default character already controllable and animated, you can ease into it learning how to replace whats already there and then add on new things.
