shortest path

[LuMo]

sorry to ask this here cause its not really luaplayer-specific...
BUT
what i am trying to do, is find the shortest way though an array from enemy to player (simple Ai)

got it working in java...
tried to convert it to lua, but i get errors all over

would be great if someone is willed to help me
(i publish the source for sure afterwards)

sample of what i try:

Code: Select all

Map= {
	{8,0,0,2,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,2,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,2,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{2,2,0,2,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,1},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,1},
	{0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1},
	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9}
}

thats my map,
enemy (Ai) = 9 (pos 17/17)
player = 8 (pos 1/1)

enemy has to walk from 17/17 to 1/1 with the shortest way

the java-code solves the problem just fine (2 classes)

code can be viewed/downloaded here(bottom 3 files):
have a look here

You are right, please ask this on http://www.lua.org/lua-l.html or irc://irc.freenode.net/lua , would be too much traffic at this forum, if every general Lua question is discussed.
