Short terrain_info - the array contains characteristics of surfaces for each tile, earth, water, road, wall, etc. For example, identificators group 246-548 corresponds to textures land1a_00001-land1a_00303, these are textures of earth, trees, etc., which were described before.īyte edge_data - the array contains information about the size of the object which has texture in the array tile_id Short tile_id - contains identification elements, each identificator corresponds to its texture. Read from the beginning of the file, read the data one by one without gaps. The objects that are shown in the town in file *.map include first five data blocks. This algorithm was retrieved from the original game as much as I could understand it, though it may be changed in the later versions. Then you draw the additional animation for tiles, which have the following flag.Secondly, you should draw tiles which images can exceed the tile base.At first you should draw “flat” tiles and dynamic objects on the,.This can be neutralized by drawing additional sprites which will be shown after drawing dynamic objects. A dynamic object can be in the different parts of tile and it is drawn after the main tile is shown which can create the artifacts of imaging, for example, a cart moves above the gates.Therefore, any dynamic object should appropriately move “up”, in the simplest case for each two steps aside there is one step inward. The map is turned “inwards” and its absolute size vertically does not correspond to the horizontal size. Moving objects on isometric map needs some tricks to happen.These conditions complicate the process of drawing and create additional rules for drawing. Additional animation of tiles and objects.There are objects for passing through (archways, gates, barn).On the map there are not only static tiles of earth, grass, buildings, but also dynamic objects (people, animals, animation).This image is generated from the following tiles drawn in the correct order.Īdditional conditions that occur while drawing a town. The second image shows the order of drawing tiles on 2.5D map knowing that the higher is the tile the earlier it should be drawn.The first image shows the order of drawing tiles on 2D map for creating dimension effect.

The order for drawing tiles is shown by the following image.

In order to draw the tiles on the screen it is important to take in account the distance to it, if you just draw tiles in the order they are placed on the map you’ll get a misconvention because some part of tiles was not drawn in time.
