How to better deal with Block based games

[NoreoAlles]

Hey, i have a game in wich i create a map with a forloop wich goes through a table like this one:

Code: Select all

  blocks = {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,
              0,0,0,0,0,0,1,1,1,1,1,0,0,0,0,
              0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,
              1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,
              1,1,1,1,1,1,1,1,1,1,0,0,1,1,1,
              1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
              1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
              1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
            }

So, the problem is that my player needs to be grounded and ungrounded with the
beginCon and endCon world callbacks, wich ends with the player being ungrounded if theyre between to blocks while still the ground.

What is the problem you're trying to solve? That's not clear to me so far.

I'm also not sure what you mean by grounded/ungrounded, and I'm not familiar with the callbacks you're referring to. Are you using a library, or are you referring to functions you've written yourself? Either way, please provide more detail.

I am not using libraries, the callbacks are here.
The player is grounded if the beginCon callback collision normals on the y-Axsis are bigger then zero and the player is ungrounded when the same happens but in the endCon function. The problem that i have is, that when the player is inbetween two blocks and is more on one then the other, it gets ungrounded, while the other cube doesnt ground it.

I think we're talking about transitioning between discrete locations.

You're misusing the physics engine. You can't expect an object to travel on a platform, from block to block and between blocks, never leaving the platform, and expect Endcontact to fire.

If you change your block table into a table of tables you can skip all this loop stuff and directly use the map:

Code: Select all

blocks = {{0,0,0,0,1,0,0,0,0,0,0,0,0,0,0},
             {0,0,0,0,1,0,0,0,0,1,0,0,0,0,0},--etc...
            }

if blocks[math.floor(Playerx/blocksize)][math.floor(Playery/blocksize)]==0 then
 move()
else 
 colide()
end

Code: Select all

map = {
	{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,},
	{0,0,0,0,0,0,1,1,1,1,1,0,0,0,0,},
	{0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,},
	{1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,},
	{1,1,1,1,1,1,1,1,1,1,0,0,1,1,1,},
	{1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,},
	{1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,},
	{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,},
}

where every tile is

Code: Select all

map[y][x]

and the line is

Code: Select all

map[y]

Draw the map:

Code: Select all

tileSize = 32
for y, xs in ipairs (map) do
	for x, value in ipairs (xs) do
		if value == 1 then
			love.graphics.rectangle ('fill', (x-1)*tileSize, (y-1)*tileSize, tileSize, tileSize)
		end
	end
end

If the map has any gaps then use pairs instead of ipairs.

	{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,},

	{0,0,0,0,0,0,1,1,1,1,1,0,0,0,0,},

	{1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,},
	{1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,},

	end
end

Thanks, thats way cleaner.

You can also order things as map[x][y], which defines your map in terms of columns (map[x]) rather than rows. Use whatever works best for you.

Both systems are pretty same except that the one of them is native to "notepad writing". But you must remember the the Y is before than X.
Yes, you can write/use some transpose function and use it as you want.
