Libraries.Game.Graphics.Color Documentation

The Color class stores information about a color used by the game engine. Colors are stored as a combination of red, green, blue, and alpha (or opacity). All four values may be set from 0 to 1, where 0 represents the total lack of a color or full transparency, and 1 represents full presence of that color or total opacity.

Example Code

use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color
use Libraries.Game.Game

class Main is Game

    Drawable rectangle1
    Drawable rectangle2
    Drawable rectangle3

    Color blue
    Color yellow
    Color glassy

    action Main
        StartGame()
    end

    action CreateGame
        blue:SetColor(0, 0, 1, 1)
        rectangle1:LoadFilledRectangle(100, 50, blue)

        yellow:SetColor(1, 1, 0, 1)
        rectangle2:LoadFilledRectangle(100, 50, yellow)

        glassy:SetColor(1, 1, 1, 0.25)
        rectangle3:LoadFilledRectangle(100, 50, glassy)

        rectangle1:SetPosition(50, 50)
        rectangle2:SetPosition(200, 50)
        rectangle3:SetPosition(125, 65)

    end

end

GetBottomRight()

This action returns what color is applied to the bottom right corner of an object which is using this Color.

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Color

end

GetColorCode()

This action will return the color as an integer in the RGBA8888 format, or in other words, in the 32 bit integer, the highest 8 bits represent the red, the next 8 represent the green, the next 8 represent the blue, and the final 8 represent the alpha (which is usually transparency). This is used primarily for internal use, and most users will never need to use this action directly.

integer:

GetGreen()

This action returns the green component of this color.

use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color

        output "The green value is " + color:GetGreen()
    end
end

GetHashCode()

Return

integer: The integer hash code of the object.

Example

integer hash = o:GetHashCode()

GetHexColorWithAlpha()

This action returns a 8-character hexadecimal string representing this color. The color is made of red, green, blue, and alpha components, each of which is represented by two hex characters (in that order). Some formats do not uniformly support alpha values for hex color codes, such as SVGs. If you need a hex string that does not include alpha information, use "GetHexColorWithoutAlpha()" instead.

Return

text: A 8-character hex string representing the RGBA components of this color.

Example

use Libraries.Game.Graphics.Color

Color color
color:SetColor(0.0, 1.0, 1.0, 0.70)

// This will output "00FFFFB2", representing no red, full green and blue, and 70% opacity
output color:GetHexColorWithAlpha()

GetHexColorWithoutAlpha()

This action returns a 6-character hexadecimal string representing this color. The color is made of red, green, and blue components, each of which is represented by two hex characters (in that order). This does not include any information on the alpha component. This is useful for formats that do not uniformly support alpha values for hex color codes, such as SVGs. If you need a hex string that does include alpha information, use "GetHexColorWithAlpha()" instead.

Return

text: A 6-character hex string representing the RGB components of this color.

Example

use Libraries.Game.Graphics.Color

Color color
Color red = color:Red()

// This will output "FF0000", representing full red and no green or blue
output red:GetHexColorWithoutAlpha()

GetRed()

This action returns the red component of this color.

Return

number:

Example

use Libraries.Game.Graphics.Drawable

        output "The red value is " + color:GetRed()
    end
end

GetTopLeft()

This action returns what color is applied to the top left corner of an object which is using this Color. Note that for a Color object, the returned value is the same Color object from which the action was called, and all four corner actions (GetTopLeft(), GetTopRight(), GetBottomLeft(), and GetBottomRight()) return the same value.

Return

Libraries.Game.Graphics.Color: The Color object that the action was called from.

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Color
use Libraries.Game.Graphics.Gradient

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame

        color = color:Orange()
        
        Color corner = gradient:GetTopLeft()
        output "The color's values are: " + corner:GetRed() + ", " + corner:GetBlue() + ", " + corner:GetGreen() + ", " + corner:GetAlpha()
    end

end

GetTopRight()

This action returns what color is applied to the top right corner of an object which is using this Color. Note that for a Color object, the returned value is the same Color object from which the action was called, and all four corner actions (GetTopLeft(), GetTopRight(), GetBottomLeft(), and GetBottomRight()) return the same value.

Return

Libraries.Game.Graphics.Color: The Color object that the action was called from.

  • number alphaValue

Example

use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color
use Libraries.Game.Game

        rectangle:LoadFilledRectangle(100, 50, orange)
        rectangle:SetPosition(50, 50)
        Add(rectangle)
    end
end

SetColorFromCode(integer code)

This action is used internally by the game engine to set a color using an integer value representing a color. Most users will never need to use this action directly.

Parameters

  • integer code

SetGreen(number gVal)

This action sets the green component of this color. The value passed should be between 0 and 1, where 0 represents a total lack of green, and 1 represents a full presence of green.

Parameters

  • number gVal

Example

use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color
use Libraries.Game.Game

class Main is Game

    Drawable rectangle

    Color green

    action Main
        StartGame()
    end

    action CreateGame
        green:SetGreen(1)
        green:SetAlpha(1)
        rectangle:LoadFilledRectangle(100, 50, green)
        rectangle:SetPosition(50, 50)
        Add(rectangle)
    end
end

SetHexColor(text hexValue)

This action sets the color using a hexadecimal string. The hexadecimal string must be 6 or 8 hex characters long, and can optionally be preceded by a pound symbol ("#"). From left to right, the color will use each set of 2 hex characters to set the red, green, blue, and alpha components, in that order. If there are only 6 characters, the alpha will be set to 1.0 (fully opaque).

Parameters

  • text hexValue: 6 or 8 hexadecimal characters, which can optionally have a "#" at the front

Example


use Libraries.Game.Game
use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color

class Main is Game

    action CreateGame
        // This hex value represents full red, no green, and full blue.
        text hexValue1 = "FF00FF"

        // This hex value represents no red, full green, and some blue. The alpha value is set to roughly half-transparency.
        // Note that the text isn't case sensitive, so lowercase "f" and uppercase "F" are the same thing.
        text hexValue2 = "#00ff4588"

        // Loading our hex values into a pair of colors.
        Color color1
        color1:SetHexColor(hexValue1)
        Color color2
        color2:SetHexColor(hexValue2)

        // Loading drawables using our new colors, as an example of what the loaded colors look like.
        Drawable box1
        box1:LoadFilledRectangle(100, 100, color1)
        Add(box1)
