Instead of defining 10 different bmaps with 10 names, I'd like to just run a loop to access the bmap from an array. I originally defined the array like this: Code: BMAP* pages[10] = {"page1.bmp", "page2.bmp", ..., "page10.bmp"}; but the script will not compile due to a syntax error. So instead I tried: Code: STRING* pages[10] = {"page1.bmp", "page2.bmp", ..., "page10.bmp"}; and again, the script did not complile due to a syntax error. The problem seems to be the double quotes need to be single quotes because when i changed them, it compiled however the bmap was not changed. For some reason using this line: Code: story.bmap=pages[0]; the bmap is not displayed I really want to use an array to make my life easier but I don't know why it's not working.

If you want to achieve that, you could do the following: Code: #define NUM_BMAPS 10 BMAP* bmapArray [NUM_BMAPS]; void bmapArray_startup () { int i; for (i = 0; i < NUM_BMAPS; i++) { char filename [256]; sprintf(filename, "page%d.bmp", i); bmapArray[i] = bmap_create(filename); } } to fill the array on game startup (_startup functions are always call on engine startup!). If you want to have an array of strings, you could do the following with a TEXT object: Code: TEXT* pageFilenames = { string ("page0.bmp", "page1.bmp", "page2.bmp", "page3.bmp"); } and access it with e.g. Code: (pageFilenames->pstring)[1] ( == "page1.bmp") I hope you get the idea Last edited by HeelX; 03/04/14 19:07.

I never thought to do it the first way, but it seems to be the most logical so that's what I want to do, however I've run into a bit of an issue. I went through the code to understand it, and I know what is supposed to happen, however the results that i'm getting say otherwise. First off, sprintf is not a valid function (i know it is in c++ but apparently not this engine, without external files) so I thought maybe you meant str_printf but that might be what's causing this issue. Right after that call I can an error saying invalid function arguments. With that, I decided to print the string on screen to see what was coming from str_printf and it is just random letters and symbols, hence why the bmap is not loading. Of course, as soon as I posted a response, I figured it out. The problem was in fact str_printf. All I had to do was include stdio.h, change it back to sprintf and it works. Thanks man.
