Hey there !

Im developing a little Duengon crawler since a few months and finnaly i wanna to make my game look better using autotiling. I never did this before and my first few trys were horrible i wrote like thousands of lines and it didn't worked either . Im giving my game some depth using isometric tiles for the walls so it looks kinda 2d and 3d together.

So let's get back to the topic, my main Problem is that my current Autotiling System is very large and full of if else statements. I begin with the floor and check if there's a wall nearby and if there's of i place the right tile there. But sometimes it don't work mostly where the walls are crossing. What's the best way to start, and what should I check ? Should I check for walls or even for floor tiles ? Could anyone give me an example how I could implement Autotiling for Isometric duengons ?

To understand how my game looks like here's an very old Video :



As you can see there sometimes a few tiles which aren't fitting. Mostly as I said before on crossings... I also can show some Code but that would be a huge amount of lines :/

Thanks for your help and I hope someone is reading this ^^

Hey TheChubu !

First thanks for your reply and your praise ^^ Yeah sure :

So first some reading stuff, im using libgdx if that matter. I am using three different layers. First the brick background, than the normal wall layer and an other layer for the different parts of the wall like crossings. For creating the normal wall layer i do that :

for(int y = 0; y < copyOfMap.length; y++){
		  
		  for(int x = 0; x < copyOfMap[0].length; x++){
			  
			  if(copyOfMap[y][x] == 1 ||
				 copyOfMap[y][x] == 4 ||
				 copyOfMap[y][x] == 10){
					

					if(x < 49 && y < 49 && x > 0 && y > 0){
						
						
						
						// 0 = up, 1 = left, 2 = down, 3 = right
						boolean[] directions = new boolean[4];
						// 0 = right top corner, 1 = right bottom corner, 2 =  left top corner, 3 = left bottom corner
						boolean[] corners = new boolean[4];
						
						// got an under neighbour
						directions[2] = copyOfMap[((int) y)-1][(int) x] == 2  ; 
							
						// got an upper neighbour
						directions[0] = copyOfMap[((int) y)+1][(int) x] == 2;
							
						// got an left neighbour
						directions[1] = copyOfMap[((int) y)][(int) x-1] == 2;
											
						// got an right neighbour
						directions[3] = copyOfMap[((int) y)][(int) x+1] == 2;
						
						corners[0] = copyOfMap[y+1][x+1] == 2;
						
						corners[2] = copyOfMap[y+1][x-1] == 2;
							
						corners[3] = copyOfMap[y-1][x-1] == 2;
							
						corners[1] = copyOfMap[y-1][x+1] == 2;
						
						
						
						if(directions[3] && !directions[1] && !directions[2] && !directions[0]){
							
							if(!corners[0]){
								
								region = game.manager.get("DuengonGainersAtlas/DuengonGainersAtlas",TextureAtlas.class).findRegion("Duengon-WallSet");
			                    region.setRegion(0, 0, 32, 32);			                  
		
			                    wallLayer.add(region, ((x*100)+100)/Box2dVars.UNIT, (y*100)/Box2dVars.UNIT,100/Box2dVars.UNIT,100/Box2dVars.UNIT);
								
							}
							else if(!corners[1]){
								
								region = game.manager.get("DuengonGainersAtlas/DuengonGainersAtlas",TextureAtlas.class).findRegion("Duengon-WallSet");
			                    region.setRegion(0, 64, 32, 32);
		
			                    wallLayer.add(region, ((x*100)+100)/Box2dVars.UNIT, (y*100)/Box2dVars.UNIT,100/Box2dVars.UNIT,100/Box2dVars.UNIT);
								
							}

I hope you understand my code, so im looping through the floor tiles. Than im checking for each of them if the floor tile got neighbours which are walls, if yes do the stuff there. There much more if else statements but it would be too long to put them all in here. Because sometimes there problems with my Autotiling system i created a third layer for the problem tiles. This time im looping through the wall tiles and looks if the tile got an floor neighbour. That looks like so ::

for(int y = 0; y < copyOfMap.length;y++){
		 
		 for(int x = 0; x < copyOfMap[0].length;x++){
			 
			 switch (copyOfMap[y][x]) {
			 
			case 2:
				
				if(y > 0 && x > 0 && y < 49 && x < 49){
				
					// 0 = up, 1 = left, 2 = down, 3 = right
					boolean[] directions = new boolean[4];
					// 0 = right top corner, 1 = right bottom corner, 2 =  left top corner, 3 = left bottom corner
					boolean[] corners = new boolean[4];
					
					// got an under neighbour
					directions[2] = copyOfMap[((int) y)-1][(int) x] == 2; 
						
					// got an upper neighbour
					directions[0] = copyOfMap[((int) y)+1][(int) x] == 2;
						
					// got an left neighbour
					directions[1] = copyOfMap[((int) y)][(int) x-1] == 2;
										
					// got an right neighbour
					directions[3] = copyOfMap[((int) y)][(int) x+1] == 2;
					
					corners[0] = copyOfMap[y+1][x+1] == 2;
					
					corners[2] = copyOfMap[y+1][x-1] == 2;
						
					corners[3] = copyOfMap[y-1][x-1] == 2;
						
					corners[1] = copyOfMap[y-1][x+1] == 2;
					
					
					
					
					
					if(directions[3] && directions[1] && !directions[0] && directions[2]){
						
						if(!corners[0] && !corners[1] && !corners[2] && !corners[3]){
							
							if(transformGrid[y-1][x] == 10){
								
								region = game.manager.get("DuengonGainersAtlas/DuengonGainersAtlas",TextureAtlas.class).findRegion("Duengon-WallSet");
			                    region.setRegion(64, 128, 32, 32);
			                    region.flip(true, false);
		
			                    wallLayer.add(region, ((x*100))/Box2dVars.UNIT, ((y*100))/Box2dVars.UNIT,100/Box2dVars.UNIT,100/Box2dVars.UNIT);
			                    
							}
							else{
								
								region = game.manager.get("DuengonGainersAtlas/DuengonGainersAtlas",TextureAtlas.class).findRegion("Duengon-WallSet");
			                    region.setRegion(64, 128, 32, 32);
			                    region.flip(false, false);
		
			                    wallLayer.add(region, ((x*100))/Box2dVars.UNIT, ((y*100))/Box2dVars.UNIT,100/Box2dVars.UNIT,100/Box2dVars.UNIT);
								
							}
							
						}

Normally there again much more if else statements, isnt there a easier way to implement autotiling into a game ? And am i doing autotiling right or are there some mistakes ? What could i do better ? :)

Thanks for your time and your help ! :D

I would go for bitwise.

Oh, and it's 'DUNGEON', not 'DUENGON' :) (Unless that means something I don't know about of course...)
