[1.1.60]LuaSurface::find_entities_filtered does not find entities of type "simple-entity" if collision_mask is specified

[FuryoftheStars]

(Edit: Forgot the game version in the title. Sorry )

I have a mod that modifies the collision mask of some entities, and for some of them it's also placing entities of type "simple-entity" with them (to give them, essentially, a secondary collision box that I can give different layers to than the main). I have a global setting to do needed cleanup operations - just in case - using the LuaSurface method of "find_entities_filtered", but in testing, the code wasn't finding any of these simple-entity's, but it's finding everything else just fine. I started playing with it and discovered that it wasn't finding any of the simple-entity's if I specified the collision_mask to filter on.

Code excerpt I ran (this will not run for you as is because some of the values are defined elsewhere, not to mention the collision mask layer and entity I'm looking for are exclusive to my mod):

Code: Select all

log("Collision layer: " .. global.artificial_tile_collision_layer)
local entities = surface.find_entities_filtered{collision_mask = global.artificial_tile_collision_layer}
log("Found entities by collision_mask only: " .. #entities)
local found = false
for _, entity in pairs(entities) do
    if entity.name == "tree-roots" then
        found = true
        log(entity.name .. " : " .. serpent.line(entity.position) .. " : " .. serpent.line(entity.prototype.collision_mask))
    end
end
if #entities > 0 and not found then
    log("None were \"tree-roots\"")
end

local tree_roots = surface.find_entities_filtered{name = "tree-roots", collision_mask = global.artificial_tile_collision_layer}
log("Found entities by name and collision_mask: " .. #tree_roots)
found = false
for _, tree_root in pairs(tree_roots) do
    if tree_root.name == "tree-roots" then
        found = true
        log(tree_root.name .. " : " .. serpent.line(tree_root.position) .. " : " .. serpent.line(tree_root.prototype.collision_mask))
    end
end
if #tree_roots > 0 and not found then
    log("None were \"tree-roots\"")
end

local tree_roots2 = surface.find_entities_filtered{name = "tree-roots"}
log("Found entities by name only: " .. #tree_roots2)
found = false
for _, tree_root2 in pairs(tree_roots2) do
    if tree_root2.name == "tree-roots" then
        found = true
        log(tree_root2.name .. " : " .. serpent.line(tree_root2.position) .. " : " .. serpent.line(tree_root2.prototype.collision_mask))
    end
end
if #tree_roots2 > 0 and not found then
    log("None were \"tree-roots\"")
end

Log output:

My expectation was that find_entities_filtered with the collision_mask parameter defined would find all matching entities, regardless of the entity type.

I do not know if this is true for other entity types, or if there are other parameters that if I define will break its ability to find them. This is as far as my testing went.

I was unable to reproduce this issue in 1.1.60.

For testing purposes i created a simple-entity with layer-13 only as suggested in the report

Prototype

Code: Select all

data:extend({
  {
    type = "simple-entity",
    name = "layer-13-ship-wreck",
    icon = "__base__/graphics/icons/ship-wreck/medium-ship-wreck.png",
    icon_size = 64, icon_mipmaps = 4,
    flags = {"placeable-neutral", "placeable-off-grid", "not-on-map"},
    subgroup = "wrecks",
    order = "d[remnants]-d[ship-wreck]-b[medium]-a",
    max_health = 200,
    collision_box = {{-1.2, -0.9}, {1.2, 0.9}},
    selection_box = {{-1.5, -1.2}, {1.5, 1.2}},
    collision_mask = {"layer-13"},
    render_layer = "object",
    pictures =
    {
      {
        filename = "__base__/graphics/entity/ship-wreck/medium-ship-wreck-1.png",
        width = 120,
        height= 85
      },
      {
        filename = "__base__/graphics/entity/ship-wreck/medium-ship-wreck-2.png",
        width = 126,
        height= 107,
        shift = {0.3, 0.1}
      }
    }
  }
})

then i created a save file with this entity and used your command with tiny modifications to adjust for the prototype name:

command

Code: Select all

/c
global.artificial_tile_collision_layer = "layer-13"
local surface = game.player.surface

log("Collision layer: " .. global.artificial_tile_collision_layer)
local entities = surface.find_entities_filtered{collision_mask = global.artificial_tile_collision_layer}
log("Found entities by collision_mask only: " .. #entities)
local found = false
for _, entity in pairs(entities) do
    if entity.name == "layer-13-ship-wreck" then
        found = true
        log(entity.name .. " : " .. serpent.line(entity.position) .. " : " .. serpent.line(entity.prototype.collision_mask))
    end
end
if #entities > 0 and not found then
    log("None were \"layer-13-ship-wreck\"")
end

local tree_roots = surface.find_entities_filtered{name = "layer-13-ship-wreck", collision_mask = global.artificial_tile_collision_layer}
log("Found entities by name and collision_mask: " .. #tree_roots)
found = false
for _, tree_root in pairs(tree_roots) do
    if tree_root.name == "layer-13-ship-wreck" then
        found = true
        log(tree_root.name .. " : " .. serpent.line(tree_root.position) .. " : " .. serpent.line(tree_root.prototype.collision_mask))
    end
end
if #tree_roots > 0 and not found then
    log("None were \"layer-13-ship-wreck\"")
end

local tree_roots2 = surface.find_entities_filtered{name = "layer-13-ship-wreck"}
log("Found entities by name only: " .. #tree_roots2)
found = false
for _, tree_root2 in pairs(tree_roots2) do
    if tree_root2.name == "layer-13-ship-wreck" then
        found = true
        log(tree_root2.name .. " : " .. serpent.line(tree_root2.position) .. " : " .. serpent.line(tree_root2.prototype.collision_mask))
    end
end
if #tree_roots2 > 0 and not found then
    log("None were \"layer-13-ship-wreck\"")
end

But it is working fine:

Edit: Is your entity "tree-roots" using collision mask "colliding-with-tiles-only"?

[boskid]

Ok, the "colliding-with-tiles-only" is the only possible explanation for the issue happening here so the issue is now fixed for 1.1.61.

Fixed LuaSurface::find_entities_filtered would fail to find entities by collision mask if they only collide with tiles. (102706)

[FuryoftheStars]

(Just as I was going to post I see your new post. I'm going to post this anyway in case it helps any. And yes, my "tree-roots" entity does have the "colliding-with-tiles-only" flag.)

Mod attached. I've made some heavy edits to it since posting, but I put the code from my OP back into it and the issue still occurs for me, even with this being the only running mod.

It appears to happen with any game: new, existing, map editor. I've added a separate global setting for the purposes of testing it and added some additional lines in the debug code to print basic results to the console (the actual per entity results are logged only, still). Just load the mod up into a game, go into mod settings and hit the "debug" setting (it's colored orange) and then exit the menu to get the results (it's set up as a "run once" per toggle).

The collision layer is created in data.lua at line 6, and the simple-entity "tree-roots" starts at line 57 in the same file. The debug code in control.lua starts at line 533, but you can just search for the triple hash ( ### ).

If you're unable to repro, then there's a good chance I mucked something up. Let me know if you find it!
