NULL, we move to the next tile and continue to do so until we encounter a tile that is not NULL. When the next input is set, we increment theĬursor's tileID. The remove input does the same thing, except that it always sets the tile's value toīLANK_TILE. We then set this tile value to the tileID of the cursor. We do the sameįor the vertical coordinate. This by taking the startX value and adding the cursor.x valueĪnd then dividing this value by TILE_SIZE to give us the nearest tile. The add input is 1, we place a tile at the current screen and mouse cursor position.
We then handle the left, right, up and down arrow key presses as per the previous tutorial. If (input.left = 1 || input.right = 1 || input.up = 1 || input.down = 1)įirst, we prevent the cursor from being able to move into the bottom row of the screen, since we will use that toĭisplay messages. * Write the data from the file into the map */Ĭursor.y = SCREEN_HEIGHT - TILE_SIZE * 2 Printf("Failed to open map %s\n", map.filename) In the next tutorial we will not perform this step. Of the size of the map would not allow us to expand the map so, we set the size of the map to the maximum possible Since this is a map editor however, limiting the scrolling to the bounds We check if the current x value is greater than the current maxX To 0 and then, while reading the map data, we check if the current map value is not the blank tile. * Set the maximum scroll position of the map */īefore reading the map data, we set the maxX and maxY values * Read the data from the file into the map */
#Tiled tutorials code#
The map loading code in map.c has changed to allow dynamic setting of the maximum The message will be displayed on the screen as long as This structure is used to display messages on the screen. The x and y variables are screen coordinatesĪnd the tileID is the current ID of the selected tile. Currently this is hardcodedīut later tutorials will see the filename stored as part of the map data. The background variable is the background image. The filename variable simply stores the path to the map data so that we can load and We have increased the maximum number of tiles to 400 x 300 and also updated the Map Pressing S will save the map data and pressing L will load the map data.
