How to Rotate Images With Tile in Java

The "TiledLayer" class in Java creates images using tiles or a layered group of images. Each section of the image is a tile and each one contains a designated index value. You can rotate the images in the tiles using the Java loop function. The loop goes through each image and moves it to the next location.

Instructions

1. Open your preferred Java programming editor and the project you want to edit. Double-click the source code file to rotate the tiles.

2. Get the tiled image's grid data and determine the number of the column and row indexes. The following code retrieves the tiled image data:

   byte[][] tiles = getGridData();
   int rows = tiles.length;
   int columns = tiles[0].length;

3. Set up a new tiled layer used to rotate the images from the current tiled layout. The following code creates a new tiled layer:

   TiledLayer newtiles = new TiledLayer(columns, rows, tiles, TILE_WIDTH, TILE_HEIGHT);

4. Rotate the images. The following code uses the Java loop to move each image to the next location in the tiled layout:

   for(int y = 0; y < rows; y++) {
   for(int x = 0; x < columns; x++) {
   int tempindex= tiles[y+1][x+1];
   if(tileIndex > 0)
   newtiles.setCell(x, y, tempindex);
   }

5. Set the new layer as the image layout. The following code uses the new "newTiles" layer to assign the new layout:

   setTiledLayer(newTiles);
