Are you able to make classes in DBPro?

If so, how would you go about making one?

DBPro doesn't support classes

I thought you were talking about classes to learn DB - which made IanM's response quiet funny .

Ah, I see.


So to control multiple things at once, while using multiple variables for each one, I could use an array instead?

Let's say I want to control the ID, X, Y, and color of 307,200 individual pixels.

Could I do that with a single array? (Or if multiple arrays for numbers 0 - 1000, etc.)

Use the TYPE...ENDTYPE statements to build a UDT, and then use that to define your array.

I'd give you the example, but your request seems a little strange to me so I probably don't understand exactly what you want...

An ID for a pixel? Surely a pixel has a colour, and a set of pixels make up a bitmap, with the pixels being identified by their X/Y coordinates within the bitmap - that equates to a 2D array of the required dimensions, holding the pixel colour and nothing more - that is simply 'DIM MyBitmap(640,480) as dword'.

Or you could create a secondary bitmap of the correct dimensions and use the DOT/POINT commands to write/read from it.

UDT?

Basically I'm making a falling sand game, and I want each pixel to have it's own ID number for referencing it's velocity, type, x, and y values.

Yes, you could say something like this:

It stands for User Defined Type. It's used to create your own array filled with different data types (instead of all strings or all integers). Neuro Fuzzy shows a UDT in his code snip.

It's equivalent to a struct. (Similar to a class, but can't support methods, basically).
