Hello,
I've loaded some images from flash and one in particular I am loading and then rotating several times. I don't understand the transform/translate stuff so I couldn't get CMD_ROTATE to work. I am using CMD_ROTATEAROUND which is fine, but even then I have to make my image square or else some part will be clipped off after rotation.
Is there a good explanation anywhere on what the CMD_TRANSLATE does, and how it interacts with CMD_LOADIDENTIY, CMD_SETMATRIX, and CMD_ROTATE?
I'm basically making the 4 quadrants of a circle by loading one quadrant image and then rotating it 3 times to complete the circle. Is it better to do that, or to have 4 quadrant images already rotated in the correct way and avoid the rotation?
So I've loaded and rotated like so:
CMD_FLASHREAD(0, 8512, 18496)
CMD_SETBITMAP(0, COMPRESSED_RGBA_ASTC_8x8_KHR, 272, 272)
BEGIN(BITMAPS)
CMD_LOADIDENTITY()
VERTEX2F(4233, 3225)
CMD_ROTATEAROUND(136, 136, 16384, 65536)
CMD_SETMATRIX();
VERTEX2F(1744, 5472)
END()
If after that I try to add:
COLOR_RGB(241, 28, 0)
CMD_TEXT(296, 152, 30, 0, "VH6C-101")
The text does not show up. I can move it above the FLASHREAD and it works. If I take out either the CMD_ROTATEAROUND or CMD_SETMATRIX it works. If I go in to the Inspector window of EVE Screen Editor I can see in the RAM_DL that there are several commands, then a DISPLAY(), then a couple more VERTEX2II commands, then the rest of RAM_DL is filled with DISPLAY(). So it doesn't seem like that first DISPLAY() should be there, right?
Also, is there any way to modify a small part of what is already drawn on screen, like changing some text or changing the color of something, without having to redo the whole display list?
Thank you for any help.
