For the game i have been making i have been using some physics to create realistic, parabolic, movments.
i first use Vf = Vi + at to find the next velocity from the last one
then i change Vi = Vf in order to create the change in velocity
then DeltaY = Vi(Sin(theta)(DeltaTime) - 1/2(Gravity(DeltaTime^2)
then DeltaX = Vi(Cos(theta)(DeltaTime)
(i love physics)
the problem is that since i am having this program run at 60 frames per second i use 1/60 for my DeltaTime, right. but the chance from one position to the next it to small becouse the time change it to small so the object dose not move becouse you cant draw part of a pixle, and if i up the time frame it of corse moves way to fast.
Any one with any tricks on the subject plz tell me and thank you for your input
