Setting the sprite color base with VideoControl()

BSzili · 18 February 2017, 16:39

I'd like to change the base color for the even sprites in a system-friendly way. I tried to use the VideoControlTags() function, but it doesn't seem to do anything:

Code:

    VideoControlTags(screen->ViewPort.ColorMap,
        VTAG_SPEVEN_BASE_SET, 0,
        TAG_DONE);

When I tried to read the default values with VTAG_SPEVEN_BASE_GET, I didn't get any meaningful result either. From what I understand I should be able to select 16 color banks, but I don't know what value to set to achieve this.

You are using an extended colormap structure, correct?

I'm using the ColorMap that's allocated by OpenScreen, but I checked the type just in case and it's 0x02.
