POAndroid dip vis pixels. Having terrible trouble with my 2d tilemap?
text
Body
copied!<p>I've searched/read all of the dip to pixel translations, but I'm feeling a little overwhelmed by it all, I'm sure it's incredibly easy to grasp, but I'm quite old school :( So I'm pleading for some help on the matter, if anyone's got the time.</p> <p>I've got an android game using a SurfaceView, which draws a 2d tilemap to the screen for a puzzle game. I've stupidly hardcoded all values for my device, just to get it up and running. Now it's pretty much 100% complete, I went out and bought a Samsung Galaxy tab, and it looks like poop! Can anyone shed some light on how to get the following code to work in dip/dp, rather than pixels please?</p> <p>TIA!</p> <pre><code> public static int MAX_WIDTH = 320; // width of map area public static int MAX_HEIGHT = 480; // height of map area public static final int TILE_SIZE_2 = 32; // tile size dimensions </code></pre> <p>I then set my map area to a pre-defined area</p> <pre><code> map_area = new int[MAX_WIDTH/TILE_SIZE][MAX_HEIGHT/TILE_SIZE]; </code></pre> <p>Here is how I setup the levels themselves (you'll see what I mean when I'm old school) - It's a shambles, I know! I do have time to waste though!</p> <pre><code> public void mapStringToMap(String mapString){ // clear the map first int i= 0; rocks = new CTile[mapString.length()]; try { // now add the rock types to the map array for(int x = 0; x<MAX_WIDTH/TILE_SIZE; x++){ for(int y =0; y<MAX_HEIGHT/TILE_SIZE; y++){ rocks[i] = new CTile(); setMapData(x, y, Integer.parseInt(String.valueOf(mapString.charAt(i)))); rocks[i].setRockType(Integer.parseInt(String.valueOf(mapString.charAt(i)))); rocks[i].setX(x*TILE_SIZE); rocks[i].setY(y*TILE_SIZE); rocks[i].setRockId(i); if(Integer.parseInt(String.valueOf(mapString.charAt(i))) == GOLD_TILE){ rocks[i].setRockBitmap(goldTile); // increase the number of rocks for this level level_rock_count+=3; }else if(Integer.parseInt(String.valueOf(mapString.charAt(i))) == SILVER_TILE){ rocks[i].setRockBitmap(silverTile); // increase the number of rocks for this level level_rock_count+=2; }else if(Integer.parseInt(String.valueOf(mapString.charAt(i))) == COPPER_TILE){ rocks[i].setRockBitmap(copperTile); // increase the number of rocks for this level level_rock_count++; }else if(Integer.parseInt(String.valueOf(mapString.charAt(i))) == START_TILE){ dave.setX(x*TILE_SIZE); dave.setY(y*TILE_SIZE); }else if(Integer.parseInt(String.valueOf(mapString.charAt(i))) == DIAMOND_TILE_1){ rocks[i].setRockBitmap(diamondTile1); // increase the number of rocks for this level by 4! level_rock_count += 4; } // move on i++; } } } catch(ArrayIndexOutOfBoundsException e) { e.printStackTrace(); } } </code></pre> <p>As a result, it works wonderfully on my device, but I'm trying to cover as many handsets as I can, obviously. The drawing of the maps is pretty much identical to above, the whole grid values x/y * TILE_SIZE etc. </p> <p>I'm sure I'm going to kick myself, but I just can't wrap my head around anything I've read.</p> <p>Cheers.</p>
