So my first problem seems pretty straight forward. outside my while(LoopGDK()) loop i set an int variable time = 0. then i have time++; within the main while loop. I'm trying to get some text to go across the screen after a certain amount of time, but once I try to make time > 300 for the trigger to do this, it doesn't work. Whenever I make the trigger at or before 300 it works fine.

also, I am trying to simulate gravity for when the main character in the 2d game im making is not touching the ground. i tried doing something similar to a time incrementation and doing dbMoveSprite() where the value starts at say 5 and decrements .01 each time. this doesn't seem to do anything. Another solution i thought of was instead of simulating gravity, just do like a cosine curve from 0 to 90 degrees maybe? I can't seem to solve this no matter what I try.

another problem I had with music. two of my mp3 files work and two did not. the two that didn't are bigger so this is the only thing I can think of as to why it wouldn't work. this is my smallest problem and not really a big deal.

any help would be appreciated, can post code if necessary.

Without a snippet for your time problem there's not much to say apart from speculate.

For your dbMoveSprite() problem, are you using 'float' variables instead of 'int'? Also the gravity can be solved just by decrementing the Y coord each frame by a certain value. You may have to do checks on the Y coord to make sure it doesn't go out of range, and collisions, etc.

Your MP3 problems I'm not sure, have you tried playing them from DBP and seeing if they work with that? Could be anything from a bitrate format not being compatible, not sure. Anyhow, if you are still needing them, then you could google the bass.dll which plays almost any music file. You will have to include the bass.dll in your executables directory but it does come with a header file which you can include in your source.

here is the code I have so far.

https://gist.github.com/2564003

if anything is confusing let me know. I didn't include any of the header files, just the cpp's. Also, Im not done yet, I still have to add in player deaths, some sort or point system, and make it so the speeds increase with each new stage (in addition to the problems I am asking about). I can't even do these last two until my in game timer works, something that should be simple but isn't working for me.

ANY sort of help would be massively appreciated because I really can't get it.
