Hardon Collider not detecting collision

[munchor]

Yeah, it works for me too, now even stranger :S I'm really confused, what a mystery.

[Kadoba]

maps[1].tl["ground"] isn't nil for me. How are you testing it?

[munchor]

Neither to me, but I get this:

Code: Select all

main.lua:72: attempt to call method 'iterate' (a nil value)

[Kadoba]

map[1].tl["ground"].tileData.iterate is there for me. Can you upload another .love?

[munchor]

map[1].tl["ground"].tileData.iterate() works for me. Can you upload another .love?

I forgot .tileData.

Attached is a .love.

Code: Select all

ERROR: AdvTiledLoader/Grid.lua:57: attempt to index local 'self' (a nil value)

I'm getting that error, and it is being reported somewhere in this function:

Code: Select all

function get_solid_tiles(map)
  local collidable_tiles = {}

  local layer = map.tl["ground"]

  for tileX, tileY, tile in layer.tileData.iterate() do

      if tile and tile.properties.solid then
        local ctile = collider:addRectangle((tileX - 1) * 16, (tileY - 1) * 16, 16, 16)
        ctile.type = "tile"
        collider:addToGroup("tiles", ctile)
        collider:setPassive(ctile)
        table.insert(collidable_tiles, ctile)
      end

  end

  print(#collidable_tiles)
end

Thanks in advance!

Iterate needs to be called using a colon instead of a period.

Code: Select all

function get_solid_tiles(map)
  local collidable_tiles = {}

  local layer = map.tl["ground"]

  for tileX, tileY, tile in layer.tileData:iterate() do

      if tile and tile.properties.solid then
        local ctile = collider:addRectangle((tileX - 1) * 16, (tileY - 1) * 16, 16, 16)
        ctile.type = "tile"
        collider:addToGroup("tiles", ctile)
        collider:setPassive(ctile)
        table.insert(collidable_tiles, ctile)
      end

  end

  print(#collidable_tiles)
end

Thank you, that fixed it However, "if tile and tile.properties.solid then" is never being called.

By this I mean, tile.properties.solid is always "nil". I am sure I have a tileset of tiles with the property "solid" set to "1".

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" width="26" height="24" tilewidth="25" tileheight="25">
 <tileset firstgid="1" name="Tiles" tilewidth="25" tileheight="25">
  <properties>
   <property name="solid" value="1"/>
  </properties>
  <image source="tileset.png" width="50" height="50"/>
 </tileset>
 <layer name="ground" width="26" height="24">
  <properties>
   <property name="ground" value="1"/>
  </properties>
  <data encoding="base64" compression="zlib">

  </data>
 </layer>
</map>

There's .tmx file, attached is yet another .love.

You had the solid property in your layer set to 1, but not in the individual tiles.

[munchor]

You had the solid property in your layer set to 1, but not in the individual tiles.

Ah, I get it. I managed to make it work. I'll just use "layer.properties.solid", instead of setting each tile to "solid".

Thank you tons for the help!

I'm trying to get working this example but I'm not capable to get the player collide with the map. Can someone put a .love where we can see the player colliding with the map?

aaand

jejeje how can i get the point where the collide or collision is done... perhaps to put a flame on the correct side or some sparks ? crash!

sorry for my poor english
