Trajectory of Bullet

[platky]

Im having a new problem with my trajectory of my bullets. I have only done some incredibly simple attempts at getting the trajectory right but its just not accurate as you will clealry see if you try my game. I know there is a way or some equation/method to do this i just cant think of anything that would properly work. If you have any suggestions please help...

The horizontal distance the bullet has traveled:

code:

d = vt

where d = distance; v = speed of bullet; t = time since bullet launched.

The vertical distance the bullet has traveled:

code:

d= vt + 0.5at^2

where a = acceleration due to gravity = -9.8 on Earth.

BTW, you're using far too many global variables in your program. Have you read up on parameters in http://compsci.ca/v3/viewtopic.php?t=14665? Doing so would really help you write cleaner, easier to maintain code .

thanks i got it to work well enough and the reason for the mess of variables is because everything is really makeshift and i just keep adding. I dont feel like cleaning it up yet...

BTW, the v in the first formula should be the horizontal speed, and the v in the second formula should be the vertical speed. Just thought I'd clear that up for anyone reading.
