Food/water graphics?

This is the codes in the render.lua, but I forgot what was needed to make the codes go from displaying simple lines of color to graphics... heh I am still relearning again blah...So how can I change this into what is needed for lets say water_bar.bmp and food_bar.bmp to be shown?
Code: Select all
-- A subrenderer for the main inventory
function sys_render_mainsub(who)
local sr = dsb_subrenderer_target()
dsb_bitmap_clear(sr, base_background)
dsb_bitmap_draw(gfx.inter_foodwater, sr, 6, 0, false)
local baseval = dsb_get_food(who)
local barlen = math.floor((192 * baseval) / 3072) - 1
local ccolor = adjust_bar(baseval, {148, 72, 0})
dsb_bitmap_rect(sr, 28, 38, 30+barlen, 51, {0, 0, 0}, true)
dsb_bitmap_rect(sr, 24, 34, 26+barlen, 47, ccolor, true)
baseval = dsb_get_water(who)
barlen = math.floor((192 * baseval) / 3072) - 1
ccolor = adjust_bar(baseval, {0, 0, 255})
dsb_bitmap_rect(sr, 28, 84, 30+barlen, 97, {0, 0, 0}, true)
dsb_bitmap_rect(sr, 24, 80, 26+barlen, 93, ccolor, true)
end
-- Utility function for coloring the bar
function adjust_bar(val, default)
local rv
if (val < 512) then
rv = {255, 0, 0}
elseif (val < 1024) then
rv = {255, 255, 0}
else
rv = default
end
return rv
end

If you pass a
dsb_bitmap_rect a bitmap instead of a color table (i.e.,
gfx.food_bar instead of
{148, 72, 0}) it will tile that bitmap instead of drawing a solid colored rectangle. This is how we did it last time, I think.
Allegro doesn't let you tile bitmaps with any sort of transparency or masked (power pink) backgrounds so DSB doesn't either. The easiest way to get around this is to make a solid background color and make your tiled bitmap's background color the same as your main background color. This is also what we ended up doing last time.
I hope this helps.

Probably I misunderstood the problem, but what's with masked_blit and subbitmaps in Allegro?

I don't know... what is with them?
(I don't understand what you're asking!)

Well, I thought those are able to handle transparency.

They are! But for
dsb_bitmap_rect I'm using DRAW_MODE_COPY_PATTERN with rectfill, which isn't able to handle it.
I could work out something with
masked_blit, but then I'd have to tile the bitmap myself. I already do it with the code to draw blue hazes, so I could adapt it... but I didn't feel like bothering.

After all the time, I still didn't find hours left over to spend for working with DSB. And I'm sure that I'll be stuck within DM2-things for another while. It's a shame, I know - but I'm somewhat stubborn in my todo-list (Paul says nuts, probably even fits better).
If Kesa found a way, it's okay anyways.
