We need an icon that should be used both as an icon for the binary and as the icon for the window when running Liero. See discussion in #2 for suggestions on icon to use and requirements on it.

$ cmake -G 'Unix Makefiles' ..
CMake Error at CMakeLists.txt:7 (find_package):

@ahockersten could you explain what exactly this code in worm.cpp doing?

if(reacts[RFDown] < 2)
				{
					if(reacts[RFUp] > 0)
					{
						if(reacts[RFLeft] > 0 || reacts[RFRight] > 0)
						{
							//Low or none push down,
							//Push up and
							//Push left or right

							pos.y -= itof(1);
							next.y = pos.y + vel.y;
							iNext.y = ftoi(next.y);

							calculateReactionForce(game, iNext.x, iNext.y, RFLeft);
							calculateReactionForce(game, iNext.x, iNext.y, RFRight);
						}
					}
				}

				if(reacts[RFUp] < 2)
				{
					if(reacts[RFDown] > 0)
					{
						if(reacts[RFLeft] > 0 || reacts[RFRight] > 0)
						{
							//Low or none push up,
							//Push down and
							//Push left or right

							pos.y += itof(1);
							next.y = pos.y + vel.y;
							iNext.y = ftoi(next.y);

							calculateReactionForce(game, iNext.x, iNext.y, RFLeft);
							calculateReactionForce(game, iNext.x, iNext.y, RFRight);
						}
					}
				}
			}

Is it special code for climbing? If not, do you know part of code, which handle moving by ascending surface?
Very appreciate any information. Thanks for great port of awesome game!

There needs to be a way to generate maps. There are a few old and perfectly ok options for this, but they are quickly becoming outdated.

I see a few alternatives:

1. Find an existing tool and recommend that (Liero Hellhole has several)
2. Create or port something that can convert existing bitmaps to Liero levels
3. Enable Liero to read image files of the correct size/format directly

To complicate option 3 there needs to be a way to get an image of the map as it is displayed inside Liero, which is not the same as the source image (since it applies textures and whatnot).

I would really like to have something like option 3 for ease of use and for easy testing of new maps.

While doing this, it's worth considering expanding the scope of maps to include stuff like using all available colors and adding new types of terrain (for example, while there is terrain that can be shot through but not moved through, I believe there's no terrain that can be moved through but not shot through).

I don't like the fact that the source code is placed directly in the root of the repository. It should get moved.

It would be nice if README.md mentions the instructions how to convert TC. Something like this: https://www.reddit.com/r/linux/comments/3u9hna/how_to_get_liero_v136_running_on_linux/

Hey, not sure if this is the right place, but I just wanted to let you know about one issue which I discovered about Liero orbmit edition.
Some Liero soundpacks (.snd files) are missing (mostly intentionally) single sounds, e.g. a soundpack in Liero TC called Tank Wars II by Runestorm is missing DROPSHELL and BURNER sound. However, you can still run such TCs normally (either using 1.36 openliero.exe or without it, e.g. when you run liero.exe in dosbox) and this has no impact on the game - even if you set such "empty" sound as a launch sound for any weapon, the game will not crash.
However, when you convert such TC (with such "incomplete" soundpack) to the 1.38+ orbmit version, the game will crash when you try to open this TC in the game. After conversion, the "missing" sound is in fact represented as empty .wav file in the TC/X/sounds subdirectory, but the game cannot read it and the game crashes (with no "warning message" printed).
PS. big respect to you guys for making Liero still alive & developing it, you are the best!
