Trouble with print fonts to screen.
Author
I am making a tetris clone and I'm doing fine with drawing sprites for the blocks, but printing text to the screen is doing something weird.
If I print the font, and don't draw any sprites the font draws right where it should, but if I draw the sprites and draw the fonts it draws positioned relative to the moving block sprite. It also moves along with the block when I control it with the keys. All relevant code is posted below.
I can't figure out why the font is drawn this way.

That's probably not true.
If draw_map() somehow uses spriteobj, try putting a spriteobj->Flush() call after the draw_map() function.
Alternately, don't use the sprite to draw the text. Use font->DrawText(NULL,...).

I'll try your two suggestions and see what I get.
And no I'm not doing any transformation to the sprites.

void Sprite_Transform_Draw(LPDIRECT3DTEXTURE9 image, int x, int y, int width, int height, int frame, int columns, float rotation, float scaling, D3DCOLOR color){ //create a scale vector D3DXVECTOR2 scale( scaling, scaling ); //create a translate vector D3DXVECTOR2 trans( x, y ); //set center by dividing width and height by two D3DXVECTOR2 center( (float)( width * scaling )/2, (float)( height * scaling )/2); //create 2D transformation matrix D3DXMATRIX mat; D3DXMatrixTransformation2D( &mat, NULL, 0, &scale, ¢er, rotation, &trans ); //tell sprite object to use the transform spriteobj->SetTransform( &mat ); //calculate frame location in source image int fx = (frame % columns) * width; int fy = (frame / columns) * height; RECT srcRect = {fx, fy, fx + width, fy + height}; //draw the sprite frame spriteobj->Draw( image, &srcRect, NULL, NULL, color );}Using font->DrawText(NULL,...) worked, however using spriteobj->Flush() after drawMap() did not change anything.
Quote:spriteobj->SetTransform( &mat );
This transform was being applied to the font call. That's why font->Draw(NULL...) fixed the problem.
When you set a sprite transform, it's applied to anything drawn by the sprite thereafter.
