[1.1.34] Modding: graphics errors with layered recipe icons.

[everything-narrative]

Description

The bug manifests as a strange rendering of recipe icon generated using the

Code: Select all

icons

property for layered icons.

First, when rendering on an assembler in alt-mode, the top layer isn't properly shadowed:

Second, when rendering in the crafting menu, the icon spills out of bounds:

How to replicate

A mod with the following `data.lua` file was used to generate this error

Code: Select all

data:extend{
  {
    type='recipe',
    name='crush-brick',
    enabled='true',
    ingredients = { { 'stone-brick', 1 } },
    result = 'stone',
    energy_required = 0.5,
    category = 'advanced-crafting',
    icon_size = 64,
    icon_mipmaps = 4,
    icons = {
      {
        icon = '__base__/graphics/icons/stone-brick.png',
        icon_size = 64,
        icon_mipmaps = 4,
        scale = 0.3,
        shift = {-7, -7},
      },
      {
        icon = '__base__/graphics/icons/stone.png',
        icon_size = 64,
        icon_mipmaps = 4,
        scale = 0.3,
        shift = {7, 7},
      },
    },
  }
}

Expected behavior

The alt-mode recipe graphic should be properly outlined in shadow to maximize legibility.

Additionally, the recipe icon should at the very least be clipped to fit within the recipe "button."

Further complaints

The documentation for the `Types/IconData` is ambiguous on the exact behavior of the `scale` and `shift` properties.

Thanks for the report.
None of this is a bug. Icon layers are borderline unusable except for the case in vanilla for which they were added (barrel recipes) but that's not a bug.

I am considering redesigning icon layer definitions for the expansion, though.

Could this note be added to the documentation?

Icon layering was designed for barrel recipes, and are not feature-rich enough to create general icon graphics. It is recommended to use image editing software for the creation of new icons.

Another limitation seems to be when layers icons need to fade. I saw two cases:

• Alerts flashing
• The "filtered" slots in an assembler that's faded.

Each layer is faded individually, meaning where they overlap is a brighter spot. Looks kinda odd.



I just took a few hours to untangle my 8 icons into a modular and easy-to-use system. Guess I need to change it back
