From cd8d88b23a2c9a5f0a3df949f57ff81a44b6aa94 Mon Sep 17 00:00:00 2001 From: sparky4 Date: Thu, 26 Jan 2017 15:02:24 -0600 Subject: [PATCH] showing row and colum drawing i optimized it to only draw at the end of walk. this explains why it is much slower than it was before panp is now sp and p is back to it self 0.exe now replicates the functions of 16_spri --- src/lib/16_sprit.c | 11 ++++++----- src/lib/16_sprit.h | 4 ++-- 2 files changed, 8 insertions(+), 7 deletions(-) diff --git a/src/lib/16_sprit.c b/src/lib/16_sprit.c index c69f6694..8cac6595 100755 --- a/src/lib/16_sprit.c +++ b/src/lib/16_sprit.c @@ -99,7 +99,8 @@ void print_anim_ids(struct sprite *spri) void animate_spri(entity_t *enti, video_t *video) { #define INC_PER_FRAME if(enti->q&1) enti->persist_aniframe++; if(enti->persist_aniframe>4) enti->persist_aniframe = 1; - + const unsigned int offscreen_ofs = video->page[0].pagesize+video->page[1].pagesize;//(vga_state.vga_stride * vga_state.vga_height); + const unsigned int pattern_ofs = 0x10000UL - (uint16_t)video->page[2].data;//(vga_state.vga_stride * vga_state.vga_height); unsigned int i,o,o2; int j; int x,y,rx,ry,w,h; @@ -162,8 +163,8 @@ void animate_spri(entity_t *enti, video_t *video) // block copy pattern to where we will draw the sprite vga_setup_wm1_block_copy(); - o2 = VMEMPAGESIZE2; - o = ((uint16_t)VMEMPAGEDATA2) + (ry * video->page[0].stridew) + (rx >> 2); // source offscreen 0x10000UL - + o2 = offscreen_ofs; + o = pattern_ofs + (ry * video->page[0].stridew) + (rx >> 2); // source offscreen 0x10000UL - for (i=0;i < h;i++,o += video->page[0].stridew,o2 += (w >> 2)) vga_wm1_mem_block_copy(o2,o,w >> 2); // must restore Write Mode 0/Read Mode 0 for this code to continue drawing normally @@ -171,7 +172,7 @@ void animate_spri(entity_t *enti, video_t *video) // replace VGA stride with our own and mem ptr. then sprite rendering at this stage is just (0,0) vga_state.vga_draw_stride = w >> 2; - vga_state.vga_graphics_ram = omemptr + VMEMPAGESIZE2; + vga_state.vga_graphics_ram = omemptr + offscreen_ofs; }else{ rx=ry=w=h=0; vga_state.vga_graphics_ram = (VGA_RAM_PTR)video->page[0].data; } vga_state.vga_draw_stride_limit = (video->page[0].width + 3 - x) >> 2;//round up @@ -194,7 +195,7 @@ void animate_spri(entity_t *enti, video_t *video) // block copy to visible RAM from offscreen vga_setup_wm1_block_copy(); - o = VMEMPAGESIZE2; // source offscreen + o = offscreen_ofs; // source offscreen o2 = (ry * video->page[0].stridew) + (rx >> 2); // dest visible (original stride) for (i=0;i < h;i++,o += vga_state.vga_draw_stride,o2 += video->page[0].stridew) vga_wm1_mem_block_copy(o2,o,w >> 2); // must restore Write Mode 0/Read Mode 0 for this code to continue drawing normally diff --git a/src/lib/16_sprit.h b/src/lib/16_sprit.h index 77891d4e..8fede666 100755 --- a/src/lib/16_sprit.h +++ b/src/lib/16_sprit.h @@ -25,8 +25,8 @@ #include "src/lib/16_vrs.h" #include "src/lib/scroll16.h" -#define VMEMPAGESIZE2 video->page[0].pagesize+video->page[1].pagesize -#define VMEMPAGEDATA2 video->page[2].data +//#define VMEMPAGESIZE2 video->page[0].pagesize+video->page[1].pagesize +//#define VMEMPAGEDATA2 video->page[2].data struct sprite { -- 2.39.5
