优化鼠标 ​

鼠标加入边界判定

c
if (mx > binfo->scrnx - 1) {
    mx = binfo->scrnx - 1;
}
if (my > binfo->scrny - 1) {
    my = binfo->scrny - 1;
}
c
void sheet_refreshsub(struct SHTCTL *ctl, int vx0, int vy0, int vx1, int vy1)
{
	int h, bx, by, vx, vy, bx0, by0, bx1, by1;
	unsigned char *buf, c, *vram = ctl->vram;
	struct SHEET *sht;
	/* refresh範囲が画面外にはみ出していたら補正 */
	if (vx0 < 0) { vx0 = 0; }
	if (vy0 < 0) { vy0 = 0; }
	if (vx1 > ctl->xsize) { vx1 = ctl->xsize; }
	if (vy1 > ctl->ysize) { vy1 = ctl->ysize; }
	for (h = 0; h <= ctl->top; h++) {
		sht = ctl->sheets[h];
		buf = sht->buf;
		/* vx0～vy1を使って、bx0～by1を逆算する */
		bx0 = vx0 - sht->vx0;
		by0 = vy0 - sht->vy0;
		bx1 = vx1 - sht->vx0;
		by1 = vy1 - sht->vy0;
		if (bx0 < 0) { bx0 = 0; }
		if (by0 < 0) { by0 = 0; }
		if (bx1 > sht->bxsize) { bx1 = sht->bxsize; }
		if (by1 > sht->bysize) { by1 = sht->bysize; }
		for (by = by0; by < by1; by++) {
			vy = sht->vy0 + by;
			for (bx = bx0; bx < bx1; bx++) {
				vx = sht->vx0 + bx;
				c = buf[by * sht->bxsize + bx];
				if (c != sht->col_inv) {
					vram[vy * ctl->xsize + vx] = c;
				}
			}
		}
	}
	return;
}

之后把两个结构体关联起来 ​

c
#define MAX_SHEETS		256
struct SHEET {
	unsigned char *buf;
	int bxsize, bysize, vx0, vy0, col_inv, height, flags;
	struct SHTCTL *ctl;	//在这里添加一个接口
};
struct SHTCTL {
	unsigned char *vram;
	int xsize, ysize, top;
	struct SHEET *sheets[MAX_SHEETS];
	struct SHEET sheets0[MAX_SHEETS];
};
c
struct SHTCTL *shtctl_init(struct MEMMAN *memman, unsigned char *vram, int xsize, int ysize)
{
	struct SHTCTL *ctl;
	int i;
	ctl = (struct SHTCTL *) memman_alloc_4k(memman, sizeof (struct SHTCTL));
	if (ctl == 0) {
		goto err;
	}
	ctl->vram = vram;
	ctl->xsize = xsize;
	ctl->ysize = ysize;
	ctl->top = -1; /* 初始化为没有图层 */
	for (i = 0; i < MAX_SHEETS; i++) {
		ctl->sheets0[i].flags = 0; /* 在这里修改标志位 */
		ctl->sheets0[i].ctl = ctl; /* 在这里链接控制器 */
	}
err:
	return ctl;
}

之后在其他的函数里面调用的时候就比较简单了, 对其他函数进行修改

显示窗口 ​

c
void make_window8(unsigned char *buf, int xsize, int ysize, char *title)
{
    //这个是右上角的叉号
	static char closebtn[14][16] = {
		"OOOOOOOOOOOOOOO@",
		"OQQQQQQQQQQQQQ$@",
		"OQQQQQQQQQQQQQ$@",
		"OQQQ@@QQQQ@@QQ$@",
		"OQQQQ@@QQ@@QQQ$@",
		"OQQQQQ@@@@QQQQ$@",
		"OQQQQQQ@@QQQQQ$@",
		"OQQQQQ@@@@QQQQ$@",
		"OQQQQ@@QQ@@QQQ$@",
		"OQQQ@@QQQQ@@QQ$@",
		"OQQQQQQQQQQQQQ$@",
		"OQQQQQQQQQQQQQ$@",
		"O$$$$$$$$$$$$$$@",
		"@@@@@@@@@@@@@@@@"
	};
	int x, y;
	char c;
	boxfill8(buf, xsize, COL8_C6C6C6, 0,         0,         xsize - 1, 0        );
	boxfill8(buf, xsize, COL8_FFFFFF, 1,         1,         xsize - 2, 1        );
	boxfill8(buf, xsize, COL8_C6C6C6, 0,         0,         0,         ysize - 1);
	boxfill8(buf, xsize, COL8_FFFFFF, 1,         1,         1,         ysize - 2);
	boxfill8(buf, xsize, COL8_848484, xsize - 2, 1,         xsize - 2, ysize - 2);
	boxfill8(buf, xsize, COL8_000000, xsize - 1, 0,         xsize - 1, ysize - 1);
	boxfill8(buf, xsize, COL8_C6C6C6, 2,         2,         xsize - 3, ysize - 3);
	boxfill8(buf, xsize, COL8_000084, 3,         3,         xsize - 4, 20       );
	boxfill8(buf, xsize, COL8_848484, 1,         ysize - 2, xsize - 2, ysize - 2);
	boxfill8(buf, xsize, COL8_000000, 0,         ysize - 1, xsize - 1, ysize - 1);
	putfonts8_asc(buf, xsize, 24, 4, COL8_FFFFFF, title);
	for (y = 0; y < 14; y++) {
		for (x = 0; x < 16; x++) {
			c = closebtn[y][x];
			if (c == '@') {
				c = COL8_000000;
			} else if (c == '$') {
				c = COL8_848484;
			} else if (c == 'Q') {
				c = COL8_C6C6C6;
			} else {
				c = COL8_FFFFFF;
			}
			buf[(5 + y) * xsize + (xsize - 21 + x)] = c;
		}
	}
	return;
}

这个是绘制一个窗口

消除闪烁 ​

由于每一次在刷新图层的时候都是从最底层的位置开始刷新的, 所以会产生闪烁, 在之后的刷新的时候只刷新图层上方的颜色

c
void sheet_refreshsub(struct SHTCTL *ctl, int vx0, int vy0, int vx1, int vy1, int h0)
{
	int h, bx, by, vx, vy, bx0, by0, bx1, by1;
	unsigned char *buf, c, *vram = ctl->vram;
	struct SHEET *sht;
	/* refresh範囲が画面外にはみ出していたら補正 */
	if (vx0 < 0) { vx0 = 0; }
	if (vy0 < 0) { vy0 = 0; }
	if (vx1 > ctl->xsize) { vx1 = ctl->xsize; }
	if (vy1 > ctl->ysize) { vy1 = ctl->ysize; }
	for (h = h0; h <= ctl->top; h++) {
		sht = ctl->sheets[h];
		buf = sht->buf;
		/* vx0～vy1を使って、bx0～by1を逆算する */
		bx0 = vx0 - sht->vx0;
		by0 = vy0 - sht->vy0;
		bx1 = vx1 - sht->vx0;
		by1 = vy1 - sht->vy0;
		if (bx0 < 0) { bx0 = 0; }
		if (by0 < 0) { by0 = 0; }
		if (bx1 > sht->bxsize) { bx1 = sht->bxsize; }
		if (by1 > sht->bysize) { by1 = sht->bysize; }
		for (by = by0; by < by1; by++) {
			vy = sht->vy0 + by;
			for (bx = bx0; bx < bx1; bx++) {
				vx = sht->vx0 + bx;
				c = buf[by * sht->bxsize + bx];
				if (c != sht->col_inv) {
					vram[vy * ctl->xsize + vx] = c;
				}
			}
		}
	}
	return;
}

添加一个参数, 记录刷新的图层的层数

c
void sheet_slide(struct SHEET *sht, int vx0, int vy0)
{
	int old_vx0 = sht->vx0, old_vy0 = sht->vy0;
	sht->vx0 = vx0;
	sht->vy0 = vy0;
	if (sht->height >= 0) { /* 刷新的时候原来位置从最底层进行刷新 */
		sheet_refreshsub(sht->ctl, old_vx0, old_vy0, old_vx0 + sht->bxsize, old_vy0 + sht->bysize, 0);
		sheet_refreshsub(sht->ctl, vx0, vy0, vx0 + sht->bxsize, vy0 + sht->bysize, sht->height);
	}
	return;
}

对调用函数的地方进行修改

出新问题, 刷新的图层上方的位置的图层会进行闪烁

创建地图记录画面信息 ​

这个地图用来记录地图上的某一个点是某一个图层的像素

c
struct SHTCTL {
	unsigned char *vram, *map;//添加图层的位置
	int xsize, ysize, top;
	struct SHEET *sheets[MAX_SHEETS];
	struct SHEET sheets0[MAX_SHEETS];
};
c
struct SHTCTL *shtctl_init(struct MEMMAN *memman, unsigned char *vram, int xsize, int ysize)
{
	struct SHTCTL *ctl;
	int i;
	ctl = (struct SHTCTL *) memman_alloc_4k(memman, sizeof (struct SHTCTL));
	if (ctl == 0) {
		goto err;
	}
    //在这里对内存进行申请
	ctl->map = (unsigned char *) memman_alloc_4k(memman, xsize * ysize);
	if (ctl->map == 0) {
		memman_free_4k(memman, (int) ctl, sizeof (struct SHTCTL));
		goto err;
	}
	ctl->vram = vram;
	ctl->xsize = xsize;
	ctl->ysize = ysize;
	ctl->top = -1; /* シートは一枚もない */
	for (i = 0; i < MAX_SHEETS; i++) {
		ctl->sheets0[i].flags = 0; /* 未使用マーク */
		ctl->sheets0[i].ctl = ctl; /* 所属を記録 */
	}
err:
	return ctl;
}
c
void sheet_refreshmap(struct SHTCTL *ctl, int vx0, int vy0, int vx1, int vy1, int h0)
{
	int h, bx, by, vx, vy, bx0, by0, bx1, by1;
	unsigned char *buf, sid, *map = ctl->map;
	struct SHEET *sht;
	if (vx0 < 0) { vx0 = 0; }
	if (vy0 < 0) { vy0 = 0; }
	if (vx1 > ctl->xsize) { vx1 = ctl->xsize; }
	if (vy1 > ctl->ysize) { vy1 = ctl->ysize; }
	for (h = h0; h <= ctl->top; h++) {
		sht = ctl->sheets[h];
		sid = sht - ctl->sheets0; /* 番地を引き算してそれを下じき番号として利用 */
		buf = sht->buf;
		bx0 = vx0 - sht->vx0;
		by0 = vy0 - sht->vy0;
		bx1 = vx1 - sht->vx0;
		by1 = vy1 - sht->vy0;
		if (bx0 < 0) { bx0 = 0; }
		if (by0 < 0) { by0 = 0; }
		if (bx1 > sht->bxsize) { bx1 = sht->bxsize; }
		if (by1 > sht->bysize) { by1 = sht->bysize; }
		for (by = by0; by < by1; by++) {
			vy = sht->vy0 + by;
			for (bx = bx0; bx < bx1; bx++) {
				vx = sht->vx0 + bx;
				if (buf[by * sht->bxsize + bx] != sht->col_inv) {
					map[vy * ctl->xsize + vx] = sid;
				}
			}
		}
	}
	return;
}

这个地图里面保存了最高层的图层

c
void sheet_refreshsub(struct SHTCTL *ctl, int vx0, int vy0, int vx1, int vy1, int h0, int h1)
{
	int h, bx, by, vx, vy, bx0, by0, bx1, by1;
	unsigned char *buf, *vram = ctl->vram, *map = ctl->map, sid;
	struct SHEET *sht;
	/* refresh範囲が画面外にはみ出していたら補正 */
	if (vx0 < 0) { vx0 = 0; }
	if (vy0 < 0) { vy0 = 0; }
	if (vx1 > ctl->xsize) { vx1 = ctl->xsize; }
	if (vy1 > ctl->ysize) { vy1 = ctl->ysize; }
	for (h = h0; h <= h1; h++) {
		sht = ctl->sheets[h];
		buf = sht->buf;
		sid = sht - ctl->sheets0;//计算当前图层高度
		/* vx0～vy1を使って、bx0～by1を逆算する */
		bx0 = vx0 - sht->vx0;
		by0 = vy0 - sht->vy0;
		bx1 = vx1 - sht->vx0;
		by1 = vy1 - sht->vy0;
		if (bx0 < 0) { bx0 = 0; }
		if (by0 < 0) { by0 = 0; }
		if (bx1 > sht->bxsize) { bx1 = sht->bxsize; }
		if (by1 > sht->bysize) { by1 = sht->bysize; }
		for (by = by0; by < by1; by++) {
			vy = sht->vy0 + by;
			for (bx = bx0; bx < bx1; bx++) {
				vx = sht->vx0 + bx;
				if (map[vy * ctl->xsize + vx] == sid) {//依据当前的图层进行刷新
					vram[vy * ctl->xsize + vx] = buf[by * sht->bxsize + bx];
				}
			}
		}
	}
	return;
}

再一次添加新的参数, 刷新图层的上限, 没有必要全部刷新

c
void sheet_slide(struct SHEET *sht, int vx0, int vy0)
{
	struct SHTCTL *ctl = sht->ctl;
	int old_vx0 = sht->vx0, old_vy0 = sht->vy0;
	sht->vx0 = vx0;
	sht->vy0 = vy0;
	if (sht->height >= 0) { /* 在刷新之前进行刷新地图 */
		sheet_refreshmap(ctl, old_vx0, old_vy0, old_vx0 + sht->bxsize, old_vy0 + sht->bysize, 0);
		sheet_refreshmap(ctl, vx0, vy0, vx0 + sht->bxsize, vy0 + sht->bysize, sht->height);
		sheet_refreshsub(ctl, old_vx0, old_vy0, old_vx0 + sht->bxsize, old_vy0 + sht->bysize, 0, sht->height - 1);//只需要对移走的图层下面的位置的图层进行刷新
		sheet_refreshsub(ctl, vx0, vy0, vx0 + sht->bxsize, vy0 + sht->bysize, sht->height, sht->height);
	}
	return;
}
c
void sheet_updown(struct SHEET *sht, int height)
{
	struct SHTCTL *ctl = sht->ctl;
	int h, old = sht->height; /* 設定前の高さを記憶する */

	/* 指定が低すぎや高すぎだったら、修正する */
	if (height > ctl->top + 1) {
		height = ctl->top + 1;
	}
	if (height < -1) {
		height = -1;
	}
	sht->height = height; /* 高さを設定 */

	/* 以下は主にsheets[]の並べ替え */

				ctl->sheets[h]->height = h;
			}
			ctl->sheets[height] = sht;
			sheet_refreshmap(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, height + 1);
			sheet_refreshsub(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, height + 1, old);
		} else {	/* 非表示化 */
			if (ctl->top > old) {
				/* 上になっているものをおろす */
				for (h = old; h < ctl->top; h++) {
					ctl->sheets[h] = ctl->sheets[h + 1];
					ctl->sheets[h]->height = h;
				}
			}
			ctl->top--; /* 表示中の下じきが一つ減るので、一番上の高さが減る */
			sheet_refreshmap(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, 0);
			sheet_refreshsub(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, 0, old - 1);
		}
	} else if (old < height) {	/* 以前よりも高くなる */
		if (old >= 0) {
			/* 間のものを押し下げる */
			for (h = old; h < height; h++) {
				ctl->sheets[h] = ctl->sheets[h + 1];
				ctl->sheets[h]->height = h;
			}
			ctl->sheets[height] = sht;

				ctl->sheets[h + 1]->height = h + 1;
			}
			ctl->sheets[height] = sht;
			ctl->top++; /* 表示中の下じきが一つ増えるので、一番上の高さが増える */
		}
		sheet_refreshmap(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, height);
		sheet_refreshsub(ctl, sht->vx0, sht->vy0, sht->vx0 + sht->bxsize, sht->vy0 + sht->bysize, height, height);
	}
	return;
}
