Hello Everyone,

• I update the position of my objects every time I go through my game loop
• I have a function that calculates the number of loops per second, lets say there are 100
• I want to move my object at a constant rate of 30 pixels per second (which is already quite fast)
• This means that I should move my object 0.3 pixels per loop
• This is a problem!

How do you normally get around this? Thanks!

I have exactly the same problem as
http://www.gamedev.net/topic/559313-sdl-sdl_ttf-font-wont-load-osx-104-solved/
which he has solved, but I just don't know what he means by src folder?
At first I thought he might mean the folder where all the source files
are but that didn't work...so close to the answer but oh so far!

Sorry to reference such an old thread but http://www.gamedev.n...ering-behavior/
refers precisely to the thing I am having trouble understanding!

In

//calculate the speed required to reach the target given the desired
//deceleration
double speed = dist / ((double)deceleration * DecelerationTweaker);

How does this calculate the speed? I just cannot understand it, besides doesn't
x/a have the dimensions of time squared?
I think it should be completely different, I am obviously missing something
u-Initial (current) velocity required (what we want to calculate above)
v - Final velocity (in this case zero)
x - Distance to target "dist" in the above?
a - The acceleration, in the above a = -deceleration * DecelerationTweaker?
Constant acceleration equation:
v^2 = u^2 + 2ax
therefore
u = sqrt(2*deceleration * DecelerationTweaker*x)
Can anybody point out the error?
