Is anyone else wondering about this? >_>

Code: Select all

tile[map[y] [x]]

No, what's wrong with that?

Last time I tried that, Lua puked errors all over my console.

Code: Select all

tile[map[y] [x]]

Code: Select all

tile[ map[y][x] ]

Does that help?
tile[] is the array of prefab tile information (i presume images).
map[y][x] is the location of a tile and returns the prefab type.

Oh, now I see. I hate whitespace.

I see a couple small things around. Random comments follow:

The map has one extra '0' on the first line, and one comma at the end that doesn't go there.

You are doing 'up' and 'down' already... interesting. You will have to change 'up' soon

Remove the map_x and map_y parts. For example here:

Code: Select all

if love.keyboard.isDown( "left" ) then
   player_X = player_X - 1
   player_direction = "l"
   map_y = map_y-1
   map_x = math.max(map_x-1, 0)
   end

Leave it like this:

Code: Select all

if love.keyboard.isDown( "left" ) then
   player_X = player_X - 1
   player_direction = "l"
end

And then remove the declarations of map_x and map_y.


Also, make map_display_w and map_display_y calculated with map; move them below map= { ... and do:

Code: Select all

map = {
 -- all the 0s and 1s here, as before
}
map_display_w = #map[1]
map_display_h = #map 

That is all I could think about for now.

Bonus point: make draw_map() 'not draw nothing' when the tile inside map[x][y] is 0.

[toaster468]

Sweet! thanks, that last bit fixed my problem. OK, now what do you mean exactly in the bonus points?

[kikito]

It isn't really important, if you already have a 'background' tile for the 0, and a 'foreground' tile for the 1s.

If you don't, then you can save some work if you just leave the 0s as 'empty space'; you don't draw any tiles on the cells with 0; you just leave the black background. So your player can use the other numbers (1,2,3) as platforms and walls and the 0 for 'empty air'.

But only if you want, nothing mandatory.

[toaster468]

OK, well I don't think I need that just yet. So, how do I make my character spawn on top of the background on below it( I'm talking about layers)?

Also, whats the next step?

[kikito]

So, how do I make my character spawn on top of the background on below it( I'm talking about layers)?

You just draw it after you draw the map, so it appears 'on top' of the map. If you draw him before, he will appear 'under' the map.

Also, whats the next step?

This one: Walls.

[com_1]

I do not know whether to post it here but look at my source code.

I think that the code of the map should look like this.
Just copy and paste into your project.
