After trying and trying, I still cannot understand why the leg of character exceeds the wall but no clipping issue when I hit the wall from below. How should I fix it to make him standstill on the wall?
void initPlayer()
{
// Create texture.
hr = D3DXCreateTextureFromFileEx(d3dDevice, "player.png", 169, 44,
D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED,
D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255),
NULL, NULL, &player);
playerRect.left = playerRect.top = 0;
playerRect.right = 29;
playerRect.bottom = 36;
playerDest.X = 0;
playerDest.Y = 564;
playerDest.length = playerRect.right - playerRect.left;
playerDest.height = playerRect.bottom - playerRect.top;
}
void initBox()
{
hr = D3DXCreateTextureFromFileEx(d3dDevice, "brock.png", 330, 132,
D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED,

boxRect.right = 63;
boxRect.bottom = 30;
boxDest.X = boxDest.Y = 300;
boxDest.length = boxRect.right - boxRect.left;
boxDest.height = boxRect.bottom - boxRect.top;
}
bool spriteCollide(Entity player, Entity target)
{
float left1, left2;
float right1, right2;

if (left1 > right2) return false;
return true;
}
void collideWithBox()
{

//playerDest.Y += 50;
playerDest.Y = boxDest.Y + boxDest.height;

}
