我正在开发一款2D游戏，你可以将主角移动到平铺的2d迷宫中，并且随时只能看到迷宫的一部分。我希望迷宫背景与超级马里奥中的角色一起移动。这是我到目前为止所尝试的：
private void pictureBox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g = e.Graphics;
tileme = Resources.me;
tilewall = Resources.wall;
tilemystery = Resources.mystery;
tilefinish = Resources.finish;
tileredlock = Resources.lock_red;
tileredkey = Resources.key_red;
tilebluelock = Resources.lock_blue;
tilebluekey = Resources.key_blue;
tilegreenlock = Resources.lock_green;
tilegreenkey = Resources.key_green;
e.Graphics.DrawImage(tileme, me.GetCenterX() - 24, me.GetCenterY() - 24, 48, 48);
int px = (me.GetCenterX() - 24) / 48;
int py = (me.GetCenterY() - 24) / 48; int nx = 0; ny=0;
if(zx==0){mx=6;}else{mx=7;}
for (int j = fx; j < mx; j++)
{
ny = 0;
for (int i = fy; i < my; i++)
{
if (i < my)
{
float tileX = ((j-fx) * 48) - zx;
float tileY = ((i-fy) * 48) - zy;
int type = lines[ny,nx];
switch (type)
{
case 1:
e.Graphics.DrawImage(tilewall, tileX, tileY, 48, 48);
break;
case 2:
e.Graphics.DrawImage(tilemystery, tileX, tileY, 48, 48);
break;
case 3:
e.Graphics.DrawImage(tilefinish, tileX, tileY, 48, 48);
break;
case 4:
e.Graphics.DrawImage(tilebluelock, tileX, tileY, 48, 48);
break;
case 5:
e.Graphics.DrawImage(tilebluekey, tileX, tileY, 48, 48);
break;
case 6:
e.Graphics.DrawImage(tileredlock, tileX, tileY, 48, 48);
break;
case 7:
e.Graphics.DrawImage(tileredkey, tileX, tileY, 48, 48);
break;
case 8:
e.Graphics.DrawImage(tilegreenlock, tileX, tileY, 48, 48);
break;
case 9:
e.Graphics.DrawImage(tilegreenkey, tileX, tileY, 48, 48);
break;
case 11:
e.Graphics.DrawImage(tileplateh, tileX, tileY, 48, 48);
break;
case 12:
e.Graphics.DrawImage(tileplateh, tileX, tileY, 48, 48);
break;
}
}ny++;
} nx++;
}
try
{
Thread.Sleep(17);
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
protected override bool ProcessDialogKey(Keys keyData)
{
OnKeyDown(new KeyEventArgs(keyData));
return base.ProcessDialogKey(keyData);
}
private void Form1_keydown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Left)
{
int ml = me.moveLeft();
if (ml == 0)
{
sx = me.update(); //sx=0 means we need to scroll the object, sx=2 means we need to scroll the background
if (sx == 2) { if (zx == 0) { zx = 48; fx += -1; } zx += -12; }
sx = 0;
this.Refresh();
}
}
if (e.KeyCode == Keys.Right)
{
int mr = me.moveRight();
if (mr == 0)
{
sx = me.update();
if (sx == 2) { zx += 12; if (zx == 48) { zx = 0; fx += 1; } }
sx = 0;
this.Refresh();
}
}
if (e.KeyCode == Keys.Up)
{
int mu = me.moveUp();
if (mu == 0)
{
sy = me.update();
if (sy == 2) { if (zy == 0) { zy = 48; fy += -1; } zy += -12; }
sy = 0;
this.Refresh();
}
}
if (e.KeyCode == Keys.Down)
{
int md = me.moveDown();
if (md == 0)
{
sx = me.update();
if (sy == 2) { zy += 12; if (zy == 48) { zy = 0; fy += 1; } }
sy = 0;
this.Refresh();
}
}
}
这不起作用，而当我尝试移动背景时，奇怪的可见错误会发生。有人请帮助我。如何使它工作？如何获得我想要的效果？
