I recently found a ridge on top of my head. about 2 inches in my part line. I havent found any answers till now. I just got over a bout of poison ivy. Steriod shots, predizone and kenolog cream. No one told me of these side effects. Thank You. I also wear my glasses on top of my head, have cluster headaches and was bitten by some knats working in the yard so I have been trying to find out any info. Also some dizzy spells, strange pulling not really pain from the ridge. I will look into these side effects more. Thank You for the info.
Jackie

I think this might be a bug, but whenever I run the TexturePacker GUI the images are reordered in a random way. For instance Tile_1 has an index of 1 but it might appear in the middle of the TextureAtlas. [ image | image | image | Tile_1 | image ]

Problem here is that Tiled uses the image’s location as the Grid number.

Any help?

I can not get the transparent tiles to work either. Transparency is working in the rest of my game, but not in the TileMapRenderer

Blank screen.

I created a new a project and used this class, made a new map, made sure all paths are correct, no errors, seems to work, but nothing is drawn.

Anything I’m doing wrong?

Thanks, It’s really helpful. But can we create cube using single mesh rather than 6 for each cube because it increases rendering time.

I just can’t get my transparent tiles to work. They always show a dark color regardles if I use proper PNG file, or fill the transparent part with pure green and then set it in tile editor… Any help? I’m actually growling at the screen right now!

Hi dpk,

I’m stucked with an issue where I have to create grid of cubes eg. 32*32 grid. Here each cube has a different color and different height. So can you help me to sort it using libgdx.

I had this problem and found that the texture packer hadn’t been able to generate a pack file for my tile map (it had a single entry in it with index -1). I was probably doing something wrong, anyway my map was simple so I just made the pack file manually and it fixed the problem.

I had to reply to this as i found an indent down the front of my head about a month ago that i am 100% sure that wasn’t there before. I have also been getting alot of pressure in the front of my head and also headaches which i never ever get so yes it was very worrying. i started noticing the indent in photos before i even knew it was there. I haven’t had any trauma to the head at all to suggest the reason for this. I was stressing for about a week reading all of these sites and questions/answers. I went to the doctor yesterday to express my concern and make sure that he knew that i wasn’t crazy. I went straight for a ct scan of my skull and sinuses, very scary, i got the results back the day after and it showed no signs of tumors or tissue changing. Conclusion was that they don’t know what it is but its not serious. With the scan they did tell me that i have chronic sinus disease, which means i have a cyst in the sinus tube underneath my eye which can flare up but isnt life threatenin, this is what was causing the headaches etc. It might of been that i never noticed the indent before but all of a sudden realised it but thought it had just happened. Who knows?? Moral of the story… Stop stressing about it and reading these sites and asking questions because i worked myself up for ages just reading these sites when infact nothing was wrong. Please please just check it out!

Nice article,

I would although recommend using SVG files for the collision boundaries – Inkscape outputs this for you, so load
your map into inkscape (png from Tiled) and then draw the collisions, save as an Inkscape SVG file and create a simple
SVG parser to then create the Box2d bodies – this is what I do on iOS.

Thanks again for some great stuff!

Steve

AAH! coworker just figured it out: in your tmx file change

Not sure if this is a bug or just my not knowing how to use the tools.

Did you figure out a resolution to this? I am having the same problems. I don’t want to manually redo the index myself as this could get tedious for a few hundred maps.

this is it:

it works, when i change:

tileMapRenderer = new TileMapRenderer(map, tileAtlas, 16, 16);

to:
tileMapRenderer = new TileMapRenderer(map, tileAtlas, 32, 26);

this parameter is: “tiles per block”… so i have to take my whole world as a block!?
what does that mean? is this correct?

[my world is defined by 25 meters a 32px/meter (=800px) / i have 32 x 26 tiles, my tilesize is 18x18 px (=576 px horiz.)]

Hey david

i am using your tiledmaphelper source code.
i have the problem that evrything looks fine as long as the resolution ist above 399 x 291. if the resolution is <= 399 x 291 then only half of the tilemap gets displayed.

is it possible that there is a bug in your code?
any ideas??

you can check it out by playing with the runnable jar (for desktop pc via libgdx) of my bubble bobble prototype:
just scale the window…

http://freigabe.philweb.de/BB/2012-03-07_BubbleBobble_399x292.jar

any help apreciated!
best regards & thx for the good tutorials/tools!

I’m not sure what you mean about the floor.

Agreed on the efficiency. The code I wrote is not great. I think that part of the problem is the line combining code. It needs another phase: removing lines that are fully contained within other lines. I don’t know if it’d help, but what if it’s possible to disable friction entirely on vertical lines?
