About

Wavewall provides some functions to use inside of its lua environment. These are intended to simplify some of the more annoying or repetitive parts of creating a tileset.

convert_rgb

Function Spec

• Input: r, g, and b values: number from 0-255
• Output: a ColorInfo object

Example

color_info = convert_rgb(0, 0, 0)
print(color_info.hex) -- prints "#000000FF"

convert_rgba

Function Spec

• Input: r, g, b, and a values: number from 0-255
• Output: a ColorInfo object

Example

color_info = convert_rgba(0, 0, 0, 255)
print(color_info.hex) -- prints "#000000FF"

convert_hex

Function Spec

• Input: a hex color string
• Output: a ColorInfo object

Example

color_info = convert_hex("#000000")
print(color_info.r) -- prints "0"

create_all_pseudos

Eases the creation of pseudotiles. Given the name of an original, creates all 7 transforms with simple names.

Function Spec

• Input: string of valid tile name
• Output: table for use in pseudotiles

Example

pseudos = create_all_pseudos("original")

-- pseudos = {
--     original_90 = "90",
--     original_180 = "180",
--     original_270 = "270",
--     original_horizontal = "horizontal",
--     original_vertical = "vertical",
--     original_diagonal = "diagonal",
--     original_antidiagonal = "antidiagonal"
-- }

return {
    -- snip
    pseudotiles = {
        original = pseudos, -- or just 'original = create_all_pseudos("original")'
    }
}
