Textures

I assume you''re using NeHe''s code at the moment?

All his code does is return an int which is used to tell OpenGL which texture you want. To use a dynamic amount of textures, you just need to use something which can dynamically resize to hold data. An std::vector would work fine.

could you be a little more descriptive about the std::vector thing. is that just a generalization or what?

A standard library vector is just a fancy array of sorts. What you need are two things. 1) a way of opening a file, and parsing through it for the texture names and 2) a way to store those texture ID''s once you have them loaded. Opening a file is very easy (in windows anyway). Looking into fopen() and fread(). For storing them, it depends on how you want to use them, and if you will ever know exactly how many. For example, if you are loading all the textures in one text file, you could parse through the text file, see how many textures are there, and then create an array of that size to hold all their ID''s. Or, depending on how complicated you want to get, take it one step further and include a small amount of header information in the text file indicating how many textures are contained within it. If you need some sort of dynamic way of handling them, then I''d recommend making your own dynamic array or linked list, depending on the usage. If it''s something that you''re going to be randomly accessing all the time, you don''t want the extra expense of parsing a linked list. However if you''re just doing syncronous lookups, a linked list with an iterator would do fine.

Hope that helps, feel free to email me directly if you have any other questions about it.
