我正在尝试将其设置为角色在图 block 中的位置,当他们向上或向下移动时它会移动到下一个图 block ,但我不确定该怎么做。现在,我设置了角色移动像素的位置,但我希望它移动 1 个方格。
现在的代码是这样的,它可以工作,但在像素模式下会出现故障。我相信如果它是按 block 进行的,它可能会更好,但我还是会更改它。
float spritewidth = sprite->stretchX;
float spriteheight = sprite->stretchY;
float bushwidth = bush->stretchX;
float bushheight = bush->stretchY;
//Basic border collision
if (sprite->x <= 0)
sprite->x = 0;
if (sprite->y <= 0)
sprite->y = 0;
if (sprite->x >= 455)
sprite->x = 455;
if (sprite->y >= 237)
sprite->y = 237;
if ( (sprite->x + spritewidth > bush->x) && (sprite->x < bush->x + bushwidth) && (sprite->y + spriteheight > bush->y) && (sprite->y < bush->y + bushheight) )
{
bushcol = 1;
}
else
{
bushcol = 0;
}
if (osl_keys->held.down)
{
if (bushcol == 1)
{
sprite->y = bush->y - spriteheight - 3;
bushcol = 0;
}
else
{
bushcol = 0;
sprite->y += 3;
}
}
if (osl_keys->held.up)
{
if (bushcol == 1)
{
sprite->y = bush->y + bushheight + 3;
bushcol = 0;
}
else
{
bushcol = 0;
sprite->y -= 3;
}
}
if (osl_keys->held.right)
{
if (bushcol == 1)
{
sprite->x = bush->x - spritewidth - 3;
bushcol = 0;
}
else
{
bushcol = 0;
sprite->x += 3;}
}
if (osl_keys->held.left)
{
if (bushcol == 1)
{
sprite->x = bush->x + bushwidth + 3;
bushcol = 0;
}
else
{
bushcol = 0;
sprite->x -= 3;
}
}
最佳答案
如果您希望角色一次移动一个方 block /方 block /方 block ,只需将 Sprite 移动方 block 宽度(或高度)的像素数即可。
const int tile_width = 32; // or something
// and then
sprite->x += tile_width;
