[HELP] Unstable program speed
« on: June 12, 2015, 05:19:54 pm »
Hello, I have a problem with program speed. When the program is processing a lot of things the game slows down, and when everything settles down it goes fast again.

You can see it in the movement here:

As you can see the character dashes when the animation goes from 9 to 5, and this is probably because of the way i designed my program.  You can see the code over here:


-Something to note is, most of the features like jump and duck were before i decided to add animations but i didnt change them. so you can ignore them. i need help in either finding a new method to organize my sprites and to load them when needed, or to fix my problem of maintaining a constant program speed.
Code: [Select]

You could try using timer interrupts to set a frame limit.
If you like my work: why not give me an internet?
