physics problem
Hi,
I've got a projectile that's being affected by gravity, and it's destination is determined by crosshairs.
Unfortunately, that means I can't just use simply the coordinates of the target and the launch point to determine the angle of launch, since if I did that, because of gravity, when the projectile reached the crosshairs in the horizontal direction, it would be below them in the vertical.
one workaround was to move the crosshairs down to where the projectile was going to be, rather than where the mouse actually is, since the math seemed easier that way. That worked, but that left a large space at the top that the crosshairs couldn't reach, since while the mouse is at the top, the crosshairs are always below it.
So instead, I'm trying to do it the normal way, trying to figure out what angle I'd have to shoot the projectile at in order for it to hit wherever my mouse is. Does anyone know how to do that? Each time I try to wrap my head around the math, I just get dizzy.
