What dose square of t have to do with falling objects?
It's recursive addition (Multiplication), t * 9.8 = "speed at t".
you might take the root of speed but only to find how long it has been falling
(Incorrect thought because you would also have to account for initial
velocity).
if gravity acceleration = 900(the cvar) + gravity acceleration(One second ago)
then you would have the correct equation then.
I.E
startfall() {
my.nextthink = time + 1;
};
think() {
my.v = (static float ga = 900 + ga) + my.v;
my.nextthink = time + 1;
};
endfall() {
my.v = {my.v(0), my.v(1), 0}; // Only set vertical speed :)
my.nextthink = NEVER;
};
Is how a physics teacher might have coded it.
