    copied!<p>This script draws the controls, hero, surface and the map:</p> <pre><code>public void render(Canvas canvas) { canvas.drawColor(Color.TRANSPARENT); Drawable myImage; int tileWidth = 50; int tileHeight = 50; int rowBaseX = 0; int rowBaseY = 0; int[][] board = new int[][] { {0,0,0,0,0,0,2,0,0,0,}, {0,0,0,0,0,2,2,0,0,0,}, {0,0,0,0,0,2,0,0,0,0,}, {0,0,0,0,0,2,0,0,0,0,}, {0,0,0,2,2,2,0,0,0,0,}, {0,0,0,2,0,0,0,0,0,0,}, {0,0,0,2,0,0,0,0,0,0,}, {0,0,2,2,0,0,0,0,0,0,}, {0,0,2,0,0,0,0,0,0,0,}, {0,0,2,0,0,0,0,0,0,0,} }; int mapWidth = 10; int mapHeight = 10; for (int row = 0; row &lt; mapHeight; row++) { for (int col = 0; col &lt; mapWidth; col++) { Resources res = this.getContext().getResources(); switch(board[row][col]) { case 0: myImage = res.getDrawable(R.drawable.tile1); break; case 1: myImage = res.getDrawable(R.drawable.tile2); break; default: myImage = res.getDrawable(R.drawable.tile3); break; } int curL = rowBaseX + (col * tileWidth); int curU = rowBaseY + (row * tileHeight); int curR = curL + tileWidth; int curD = curU + tileHeight; myImage.setBounds(curL,curU,curR,curD); myImage.draw(canvas); } } droid.draw(canvas); butt.draw(canvas); butt1.draw(canvas); butt2.draw(canvas); butt3.draw(canvas); buttz.draw(canvas); buttz1.draw(canvas); buttz2.draw(canvas); buttz3.draw(canvas); buttx.draw(canvas); } </code></pre> <p>There is a hero, which has to be redrawn when player moves him with the controls, and all other drawables also has to be redrawn. The problem is that drawing a map is a long process, so the bigger map i create, the slower hero moves, because every tile of the map has to be painted. Is there a way to put all the tiles to a one bitmap in other method and draw that one bitmap in the canvas method?</p>
