problems programming a tetris clone

I already posted this one in the "beginners" forum but there is no response there as of yet so that''s why I post it again here, because I''m really desperate i''m good stuck in this game I already have a random block that I can move in my playfield now when I hit the floor (or another block) it should be placed on my playfield at that place My playfield is a 20x10 array Playfield [20] [10] and my blocks are also put in an array like this blocks = 6 ; // 7 blocks rotation = 3 ; // 4 rotations a block block [Blocks] [rotation] [4] [4] those [4] [4] are my blocks, like this by example 0000 0100 0110 0010 0100 0110 0111 0100 0110 0000 0100 0000 a 1 is for a red block, 2 purple, ..... now when I place that block in my playfield (array) I go to my function BlockInArray() and now it places that block on 3 positions in my array?!? everytime 10 blocks between and my function is only runned once (I used a timer to check) here''s my function : void BlockInArray() { x = ((Pos_X/16)-19) ; // calculate x/y y = ((Pos_Y/16)-9) ; // position in playfield for (i=0; i<4; i++) { for (j=0; j<4; j++) { if (blocks [block] [rotation] [j]) // check if there is a cube in that array { // if so position it beginning at x & y PlayField [x+i] [y+j] = blocks [block] [rotation] [j] ; } ; // end of if } ; // end of for j } ; // end of for i Pos_X = PlayfieldX+48 ; // position new block in the Pos_Y = PlayfieldY ; // middle top of playfield RandomPiece() ; } // end of BlockInArray() I''m really desperade, I''ve been breaking my head over this problem now for 2 weeks :/ Big thanx in advance if any one can help me (if you want me to send the complete code to you then send an email to s_noppe@hotmail.com or contact me on MSN or icq 3347831)
