Map generator doesn't place trees in the middle of tiles

[darkfrei]

Thanks for the report. I've improved the error for 0.17. It's actually checking that:

If you have shadows defined: shadow frame count must be == leaves frame count + 1

If you don't have shadows defined: trunk frame count must be == leaves frame count + 1

There is a lot of problems with trees:

Also, now leaf_generation and branch_generation cannot be nil, there is another error.

And this one:
If I have tree.collision_box = {{-0.7, -0.7}, {0.7, 0.7}} then I get:

2018-11-11 16_03_48-Factorio 0.16.51.png (23.57 KiB) Viewed 196 times

If I change it to tree.collision_box = {{-0.2, -0.2}, {0.2, 0.2}} then I expect:

2018-11-11 16_08_05-Factorio 0.16.51_01.png (6.47 KiB) Viewed 196 times

but I get:

2018-11-11 16_08_05-Factorio 0.16.51.png (15.36 KiB) Viewed 196 times

So I cannot place then in the middle of tiles.

It's impossible to help you, because you didn't say what you're doing.

Creating trees in middle of tiles just works:

I want to get same result, but this code cannot help me:

Code: Select all

for i, tree in pairs (data.raw.tree) do
  tree.flags = {"placeable-neutral", "breaths-air"} -- as you see,  no "placeable-off-grid" here
  tree.collision_box = {{-0.2, -0.2}, {0.2, 0.2}} -- it's less then 1 x 1 tile
end

I need exactly that, what you have on the image. But with standard autoplacement, not by the script.

I expect that all trees will be placed same way like insterters and chests, in the middle of tiles, but all of them are placed on the edge of tiles.

In the wiki you can find also this method to change the size of entity:

Code: Select all

  tree.tile_width = 1
  tree.tile_height = 1

but it's does not work.

Got it. Your expected behavior is that map generator will place entities that don't have "placeable-off-grid" aligned to grid same way as if it was built by player.

I was not sure how you were creating trees to be aligned to center of a tile (I thought you were placing them manually through script, or you tried to allow player to plant trees, or something like that ...)

The map generator places all entities (without "placeable-off-grid") less than 1x1 in the middle of tiles, all entities less than 2x2 to the lines crossing.

It works for ores, spawners, rocks another entities, but not for trees.
