Modules

how can i add some downloaded modules like minib3d into BlitzBasicMax?

Check the installation instructions that come with each module. MiniB3D for example, gives full instructions on how to install it, as do most if not all the others.

To compile the modules, your need MingW installed:

Then put the modules in the right place (see the installation instructions)
and use "Build modules" in the MaxIDE.

I found getting all the modules work not the easiest part; good luck and
ask if you get stucked!

If you downloaded a module you should find a folder named something like 'sidesign.mod' and in that a folder named (just as an example) 'minib3d.mod'. Move the 'sidesign.mod' (or whatever, again, just an example) to your blitzmax\mod\ folder.

Afterwards you can compile them using Ctrl+D in MaxIDE.
