Question by AngryBurritoCoder · Sep 01, 2015 at 06:32 PM · vector3 math bullet projectile curve

Please help, bullet drop is wrong at certain angles ?

Im creating a simple bullet trajectory script, this script creates nodes along a "to be" bullet trajectory, i use the equations for vertical and horizontal axes to find the distance the bullet travels every 1 second for around 10 seconds, that way i get a nice curve.

The problem is that at above 25 angle , the curve doesnt start at correct direction, its slightly upward, and opposite for low angles below -25 or somewhere around there, please Check picture for Explanation;

equations are :

height = initial velocity time sin(angle) + 0.5 gravity time sqr

forward = initial velocity time cos(angle)

pictures below i cant figure out whats wrong!

the curve is meant to start straight from the tube its fired, but seen in picture it starts at a higher angle , ( this happens more notibly the higher angle i aim at, same for opposite)
