Help with scroll.bas library

[Andy1966uk]

Team,

When I use the library, the screen scrolls, however the colour of the objects bleeds to the background colour.
Is there a fix for this and also the x,y,x1,y1 cordinates of the scroll window don't seem correct.

Thanks for looking into this as I am desperate for a scroll function. thx

Which library exactly?

Remember that on the spectrum the colour and the pixels are in completely separate grids - the colour is in 8x8 squares. So unless you scroll 8 pixels at a time, you have a problem aligning to the colour grid. This is why many spectrum games are very single colour in the play area.

It wouldn't be too hard to add a colour scroll routine to the library; but it would only work with Character Square size movements.

the scroll.bas library found under zbasic library, running the scroll.bas in the examples folder.

Can you post an example, please?
