Parabola problem

Malf	I can't brain. I need help with my maths, I need to know what should x be. h is the max height and d is the distance. JASS: function ParabolicMovement takes real h, real d, real x returns real // thanks to moyack for this func! local real a = -4h/(3dd) local real b = 4h/(3d) return axx + bx endfunction

Iron_Doors	If I understand correctly x should be the current timestep or whatever and it should range from 0 to 1.

moyack	no, x is a distance, in WC3meters :P This function takes as a parameters the the distance that the parabolic movement should move (d) and the maximum height the projectile will flight (h). So x is a value between 0 and d, and the function will return the height for that value. As a side note, if x < 0 or x > d then this function will return negative values. EDIT: Here's a picture:

Malf	Ahh, I get it, thanks moyack. Rep'd because I was currently trying to figure out how to solve the problem by swapping the arguments -.-
