Updated GPU functions

[pedrosgali 8]

Hey all.

 

First off, I am thoroughly loving this mod.

 

I would very much like access to better tier graphics cards, I know however that this has been (repeatedly) requested so I'll ask for this instead.

 

I noticed while writing my paint program that I can use gpu.get(x, y) to call the specific character set at position x, y so I'm assuming that there is a table somewhere with all the current screen data written to it.

 

Would it be at all possible to store the current back/foreground colours in with this data?

 

I can use gpu.getBackground()/gpu.setForeground() but that only returns the current colour not the colour of a specific pixel.

 

I honestly think that with that small change I could halve my image refresh rate and make more complex animations by only drawing pixels that need drawing, all without the need for shiny new hardware.

 

I hope you find this suggestion useful. =)

component.gpu.get(x, y) already returns the color as well.

local char, fgAsRGB, bgAsRGB, fgPaletteIndex, bgPaletteIndex = component.gpu.get(x, y)

The palette index values will be nil if the colors are not from the palette.

I see, that is awesome. The wiki might need some updates though as that says that you can only get character info.

Ah, yes, slipped through the cracks (along a bunch of other things I'm sure). Wiki updated.
