Automapping: Double Width/Height Tile Rules

[Bryan-Legend]

With the current automapping it's not possible to have a rule apply a tile that is "double wide".

So I've got some graphics from http://www.lostgarden.com/2006/07/more-free-game-graphics.html which are awesome.

Some of the tiles though are designed to be tiled two at a time. For instance the wall on this image: http://imageshack.us/photo/my-images/708/internalwalls.png/

There's no way to make a rule to automatically place these double wide tiles because the same rule gets repeated over each tile, so only the left row of tiles in the rule gets applied over and over.

There needs to be a change in the automapper logic that says that if a tile has already been set by this same rule then not to overwrite it. Maybe put it behind a flag.

Example map with rules and tiles.

Feel free to use this example map any way you'd like. You can even include it in the distro if you'd like.

FYI, I'm using this for a silverlight game that's available at http://smote.com Give it a shot.

I'd really like to see this happen so I'll put a bounty on it. I'll paypal $50 to whoever implements the fix and sends me a build before 9/30/2011.

Hello Lone-Coder,

When I understand you right, the problem is this rule http://dl.dropbox.com/u/6520164/tiled/problematic_rule.png

If you are not interested to have it repeated exactly like A-B-A-B-A-B and so on, but in a random fashion,
(example: A-A-B-A-B-B-A-B-B-B-B-A-A-B-A ... just randomly)
this ruleset will apply: http://dl.dropbox.com/u/6520164/tiled/InternalExample.zip
The random placement can be archieved by putting multiple layers for one destination layer.
Changes were only done in ruleSet1.tmx: there is now another rule1_Wall layer which has different tiles
for that given rule in that layer.

If you need to have it exact A-B-A-B (which is indeed a serious cool and needed feature), I'll give it a try on the weekend.

So the solution as of now is this:
Whenever a rule gets applied, it is previously checked if within all touched layers, this rule was not applied to the same (=overlapping) location.

Unfortunately this solution takes a lot of CPU time, so it is switched off by default.
(only needed rules should be switched on then;) This can be done by adding the property "NoOverlayingRules" set to true
to the specific map.

Here is a Windows build for tiled,
which includes a functionality to make double wide rules
in automapping possible:

This build is off my current Automapping branch,

That works perfectly Stefan. Thank you so much! You rock! I've sent over the paypal payment.
