You should've posted the difference rather than new whole version, since it's pretty big and we'd have line-by-line compare them or use diff tool. Implementation is highly sub-optimal, if you gonna use that extensively make sure to omptimize that. Yeah, I plan on optimizing later. This is just the ...

I don't really understand how I fixed it, but I changed the pathfinding function to this: function Pathfinder:find(cx,cy,ex,ey) if ex < 1 or ey < 1 or ex > #self.nodes or ey > #self.nodes then return nil end -- init and add starting node to the open list self.nodes[cx][cy].cost = 0 self....

It is based heavily on http://www.policyalmanac.org/games/aStarTutorial.htm. If you run the game and click in the top right co...

Thanks. Figured it out. I feel stupid now. haha

Hello, I am attempting to index a multidimensional array and add a property to it. I'm new to implementing OOP in Lua so maybe I'm doing something wrong there? It's breaking in the for loop. It wont let me add a property like "self.nodes[x][y].cost = 1". Any help would be greatly appreciat...
