Hi guys. I decieded to post here instead of the game board as this problem can relate to any program. Basically, I have a problem with keeping my game run at a constant speed, and hope the following code with the 2 problems is stated succintly enough.
/* all objects have a speed variable given in pixels per second, frames per second etc.
this code is supposed to make the game run equally fast on all computers since it depends
on the amount of times the logic is called per second. all objects' x-value and y-value are
floating point numbers so they can move a "fractional amount of pixels" whenever the logic is done.
Problem 1: If the logic takes long in the beginning of the game but gets faster and faster (if objects keep getting deleted as the game progresses) the calls_per_second variable will take a while to catch up and the game won't run at a constant speed.
Problem 2: If we update the calls_per_second variable whenever logic_counter increments the calls_per_second is updated 100 times per second making (or some other amount of times per second) the game runs at a constant speed, but if tons of objects get deleted within the 1/100th of a second the game will run extremely fast for the next 1/100th inducing sudden jumps in the game speed. */
volatile int logic_counter(1); // increments by one 100 times a second (via interrupt - timer function)
int cycle_counter(1); // counter incrementing by 1 each time logic is performed
do_logic(calls_per_second); // moving all objects based on the amount of times the (logic/move) functions are called per second.
if(draw_ready) do_draw(); // rhe draw_ready flag is set 50 times a second via a timer.
