Custom Bonus GUI

Mod Portal | GitHub

This Factorio mod library provides a convient method for mods to display custom bonus cards in the "Bonuses" GUI. Useful for bonuses implemented by scripts.

Features

• A remote interface to set custom bonuses for display.
• Each custom bonus may contain any number of icons and text labels.
• Each custom bonus may be attached to a force or a player.

Caveats

• When the player has no vanilla bonuses during early game, their vanilla "Bonuses" button will be disabled, even when they have custom bonuses. This mod adds a /bonus command to display the GUI in such cases.

Example

This example shows a mod example-mod providing a bonus called "Radioactivity", implemented elsewhere by script. This bonus is gained by a research called radioactivity.

script.on_event({
    -- Run when research status changes.
    defines.events.on_research_finished,
    defines.events.on_research_reversed,
    defines.events.on_force_reset
}, function(event)
    local force = event.force or event.research.force

    -- Calculate the bonus value.
    local radioactivity = force.technologies['radioactivity'].level * 0.01
    -- Put the value in storage to be used by the implementation of the bonus.
    storage.forces[force.index].radioactivity_bonus = radioactivity

    if radioactivity > 0 then
        -- Show the bonus.
        remote.call("custom-bonus-gui", "set", force, {
            name = "example-mod-radioactivity", -- prefixed to avoid conflicts
            mod_name = "example-mod",
            order = "b",
            icons = {
                {type = 'item', name = 'uranium-rounds-magazine'},
                {type = 'item', name = 'uranium-cannon-shell'},
                {type = 'item', name = 'explosive-uranium-cannon-shell'},
                {type = 'item', name = 'atomic-bomb'},
            },
            texts = {
                -- In locale file:
                -- [example-mod]
                -- radioactivity-bonus=Radioactivity: __1__ Gy
                {"example-mod.radioactivity-bonus", radioactivity},
            }
        })
    else
        -- Remove the bonus.
        remote.call("custom-bonus-gui", "remove", force, "example-mod-radioactivity")
    end
end)
