If the issue is basic-specific and not that of the right algorithm or whatever to implement, check out the help files

You should know how to implement the following in DBPro
user defined types
arrays
dynamic arrays (Every array in DBPro is dynamic, just use "array insert at bottom" and like commands)
2d arrays
basic 3d construction and camera commands
functions
subroutines
And then there's a lot of specific commands you can use, found in the command list. I would suggest you take a look at the following
sprites - (For transparent 2d images)
sound/music - (for... sound and music)
file commands - (loading and saving files/images/sounds/save games)
display commands - (screen resolution, fullscreen mode, that stuff.)
and of course, select "core commands" (all the useful stuff like sqrt(),exp(),cos(),sin(),wrapvalue(),array count() etc.)
If you're good with all of the above, then you would have almost no issue with the language barrier

, but you don't actually need to go trying to look and read through every single section at the same time. Just keep in mind that the information is there, and follow through tutorials, and most importantly - write your own 100% original code every once in a while; Following through a tutorial, it might seem like it makes sense, but odds are it'll be forgotten fast, or found confusing later.

Is't life, I ask, is't even prudence, to bore thyself and bore thy students?
