[SDL Code] Adding multiple floor colors...

Okay, this is rather simple coding change that allow you to have multiple
solid floor colors:

In wl_draw.c search for this line

Code:

byte vgaCeiling[]=

Add this block under the "vgaCeiling"-table definition:

Code:


//
// Solid floor colour
byte vgaFloor[]=
{
#ifndef SPEAR
 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19, //episode 1
 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19, //episode 2
 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19, //episode 3

 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19, //episode 4
 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19, //episode 5
 0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19,0x19  //episode 6
#else
 0xd7,0x09,0x03,0xde,0xdf,0x2e,0x7f,0x9e,0xae,0x7f,
 0x1d,0xde,0xdf,0xde,0xdf,0xde,0xe1,0xdc,0x2e,0x1d,0xdc
#endif
};


And then replace the VGAClearScreen-block with this:

Code:

/*
=====================
=
= VGAClearScreen
=
=====================
*/

void VGAClearScreen (void)
{
    byte ceiling=vgaCeiling[gamestate.episode*10+mapon];
    byte floor=vgaFloor[gamestate.episode*10+mapon];
   
    int y;
    byte *ptr = vbuf;
#ifdef USE_SHADING
    for(y = 0; y < viewheight / 2; y++, ptr += vbufPitch)
        memset(ptr, shadetable[GetShade((viewheight / 2 - y) << 3,0,0,0,0)][ceiling], viewwidth);
    for(; y < viewheight; y++, ptr += vbufPitch)
        memset(ptr, shadetable[GetShade((y - viewheight / 2) << 3,0,0,0,0)][floor], viewwidth); //0x19
#else
    for(y = 0; y < viewheight / 2; y++, ptr += vbufPitch)
        memset(ptr, ceiling, viewwidth);
    for(; y < viewheight; y++, ptr += vbufPitch)
        memset(ptr, floor, viewwidth); //0x19
#endif
}
