Do I need to find out how to write some new different way of drawing images to the screen

drawing images to the screen in a way that doesn't transform their axis?

Unfortunately not. The code achieves what I already have. Everything is drawn in the right position, the sprite appears rotated, the walls appear the right way up, BUT the axis for the world seem to be rotated in some way. When I hold right to move right, the sprite moves diagonally towards the bottom left if I have rotated a bit clockwise.

There has to be a simple answer to this, there must be something obvious I'm doing wrong here. Is how I am doing my movement wrong? I have my sprite store in a D3DXVECTOR3, it's x and y coordinates (z is there in case I wanted to do layers or some such, but it's just 0, this is why I do player01.coordinates.x, etc). When I hold right, I increment that value by a speed variable. I then draw my sprite using this:

g_pD3DXSprite->Draw(player01.returnTexture(), NULL, &D3DXVECTOR3(0,0,0), &player01.coordinates, 0xffffffff);

the code fragment you posted looks alright.
can you post more complete code that shows how you "move" your sprite ?

because if i take a stab at this in the dark( without looking at your player movement code ) i would say you need to use somethin like this:

yPosition += cos(RotationInDegrees) * speed;
xPosition += sin(RotationInDegrees) * speed;


Here is the code for movement and collision detection:



VOID UpdateSpritePosition(LPDIRECT3DTEXTURE9 texture, float xSpeedInput, float ySpeedInput)
{
D3DSURFACE_DESC spriteDesc;
D3DSURFACE_DESC wallDesc;
int spriteWidth = 0;
int spriteHeight = 0;

int wallWidth = 0;
int wallHeight = 0;

texture->GetLevelDesc(0,&spriteDesc);
spriteWidth = spriteDesc.Width;
spriteHeight = spriteDesc.Height;
float xDistance = 0;
float yDistance = 0;

if(!walls.empty())
{
for(unsigned int i = 0;i<=walls.size()-1;i++)
{
walls.texture->GetLevelDesc(0,&wallDesc);
wallWidth = wallDesc.Width;
wallHeight = wallDesc.Height;
bool testCorners = false;

if(player01.coordinates.x == walls.coordinates.x+wallWidth &&
player01.coordinates.y == walls.coordinates.y+wallHeight)
{
testCorners = true;
}

else if(player01.coordinates.x+spriteWidth == walls.coordinates.x &&
player01.coordinates.y == walls.coordinates.y+wallHeight)
{
testCorners = true;
}

else if(player01.coordinates.x + spriteWidth == walls.coordinates.x &&
player01.coordinates.y + spriteHeight == walls.coordinates.y)
{
testCorners = true;
}

else if(player01.coordinates.x == walls.coordinates.x + wallWidth &&
player01.coordinates.y +spriteHeight == walls.coordinates.y)
{
testCorners = true;
}

if(testCorners == false)
{
if((player01.coordinates.x+spriteWidth) <= walls.coordinates.x && (player01.coordinates.y+spriteHeight) >= walls.coordinates.y && player01.coordinates.y <= (walls.coordinates.y+wallHeight))
{
if((player01.coordinates.x + spriteWidth + xSpeedInput) >= walls.coordinates.x)
{
xDistance = walls.coordinates.x - (player01.coordinates.x + spriteWidth);
xSpeedInput = xDistance;
}
}
else if(player01.coordinates.x >= (walls.coordinates.x + wallWidth) && player01.coordinates.y <= (walls.coordinates.y+wallHeight) && (player01.coordinates.y+spriteHeight) >= walls.coordinates.y)
{
if((player01.coordinates.x + xSpeedInput) <= (walls.coordinates.x + wallWidth))
{
xDistance = (walls.coordinates.x + wallWidth) - player01.coordinates.x;
xSpeedInput = xDistance;
}
}

if((player01.coordinates.y+spriteWidth) <= walls.coordinates.y && (player01.coordinates.x+spriteWidth) >= walls.coordinates.x && player01.coordinates.x <= (walls.coordinates.x+wallWidth)) {
if((player01.coordinates.y + spriteHeight + ySpeedInput) >= walls.coordinates.y)
{
yDistance = walls.coordinates.y - (player01.coordinates.y + spriteHeight);
ySpeedInput = yDistance;
}
}

else if(player01.coordinates.y >= (walls.coordinates.y + wallHeight) && player01.coordinates.x <= (walls.coordinates.x+wallWidth) && (player01.coordinates.x+spriteWidth) >= walls.coordinates.x)
{
if((player01.coordinates.y + ySpeedInput) <= (walls.coordinates.y + wallHeight))
{
yDistance = (walls.coordinates.y + wallHeight) - player01.coordinates.y;
ySpeedInput = yDistance;
}
}
}
}
}

if(PacmanMovementModeEnabled)
{
player01.coordinates.x += xSpeedInput;
player01.xSpeed = xSpeedInput;
player01.coordinates.y += ySpeedInput;
player01.ySpeed = ySpeedInput;
player01.PacmanSpeed();
}
else
{
player01.coordinates.x += xSpeedInput;
player01.coordinates.y += ySpeedInput;
}
}

the sprite rendering code, how much of it did you try ?
did you try all of it ?
