If you return the whole 'hand' (e.g. return hand ) it should be ok as it is. It's already in the format { {}, {}, {}, } that the code it's returning to is expecting. You only need to enclose the returned value in a table (e.g. return {hand[specific_card]} ) where you're just returning a single card ...

Looking at this section: print("PLAYING A CARD NON AGRESSIVELY OR BASED ON RESETS"); --Resetting Variables Opponent_AI.isMultiples = false; --A little error catch to stop it returning no cards local handNum = 0; for i = 1, #hand do if( hand[i].number >= cardPile[#cardPile].number ) then ha...

Just to clarify, what is actually returned? zero, empty table, nill?

What do you see if you print the entire 'hand' table before calling the function, immediately the function starts and just before you return?

Something like this gives an angle in Radians.

If you zoom in on the font it's clear that all the straight edges are very crisp, but the curves are blurred.

I had a similar problem when using gridlocked movement (only moving single hexes in my case but similar enough). Try calculating the move_distance_x and move_distance_y between the start point and end point of the move, then use something like: if player.moving == true then player.act_x = player.act...
