I'm coming from BlitzBasic. In that program, when you load an image you assign it to a variable then you can access it by variable name. Is it possible to do this in DB? it seems that the way it works in DB is that the loaded image is assigned a number. If you have tons of images to work with it seems that would get really chaotic.

Any ideas?

You're right; DB accesses images with numbers. This is especially convenient in instances where you need one algorithm for several images. You could then use a FOR loop to access all the images.

If you really want to use names, you could just assign a variable the image number each time you declare an image. For example:

It might be neccesary to make it a global variable as well

Or a constant

Here is the first few line of my current WIP. I find this method works very well for me.



Where multiple variables are necessary, I make sure I REM the numbers used, like so ...

Why not roll a few media helper functions. Then throw them all into an include and you have your own helper library.

Like say (PB styled code)

I use User Defined Types for everything. For example, a character entity might have several objects attached to it, and several images as well. I might have character 1, with some attributes...

char(1).object
char(1).idleSound
char(1).walkSound
char(1).gumpImage

etc.

You just feed the asset number into the UDT variable and then you can access it easily. I've got 250 objects, 90 sounds, and 175 images in my current project. Referencing them by number would simply be impossible. You should always use a variable, and I always use a UDT. UDT arrays are global, by the way.


Come see the WIP!
