[AI movement] Jumping using movegravity()

[IzNoGoD]

		jump(start, end)
{
    height = end[2] - start[2];
    v0 = 275;
    t0 = v0 / getcvarint("g_gravity");
    s0 = 0.5 * getcvarint("g_gravity") * t0 * t0;
    height -= s0;
    if(height > 0)
        return false; //no jumping possible. Target too high.
    t1sq = -2 * height / getcvarint("g_gravity");
    time = int((sqrt(t1sq) + t0) * 20) / 20;
    xdist = end[0] - start[0];
    ydist = end[1] - start[1];
    xspeed = xdist / time;
    yspeed = ydist / time;
    self movegravity((xspeed, yspeed, v0), time);
    wait time;
    self.origin = end;
    return true;
} 
	

Just some math...
To change this function into fall(), just set v0 to 0, t0 to 0 or s0 to 0. (or remove all associated stuff)
