Created page with 'The type '''color''' is not a built-in type, but a struct defined in the {{classgames|Object}} class of all Unreal Engine games. The '''color''' struct is used …'

New page

The type '''color''' is not a built-in type, but a [[struct]] defined in the {{classgames|Object}} class of all Unreal Engine games.
 
The '''color''' [[struct]] is used for drawing certain things with the {{classgames|Canvas}} and {{classgames|HUD}} with a specified color that is set with the 4 members of type [[Types#Byte|byte]](or [[Types#Float|float]] for [[UE3:Object structs (UT3)#LinearColor|LinearColor]] struct) which are '''R'''(''Red''), '''G'''(''Green''), '''B'''(''Blue'') and '''A'''(''Alpha'').

'''Note:''' [[Unreal Engine 3]] games may also define other color-like structs, such as [[UE3:Object structs (UT3)#LinearColor|LinearColor]].

==Color operations==
In [[Unreal Engine 2]] there are no built-in operators for color [[struct|structs]] except a few in {{classgames|Actor}}.

===Making a color===
[[Unreal Engine 3]] provides a <code>MakeColor()</code> function in {{classgames|Object}} that can be used to make a color [[struct]] instance by passing independant RGBA components e.g. <uscript>local Color BlueColor;

BlueColor = MakeColor( 0, 0, 255, 255 );</uscript> ''this will create a blue color and assign it to '''BlueColor'''''.

'''Note:''' [[Unreal Engine 2]] doesn't have function <code>MakeColor()</code> accessible from {{classgames|Object}} but in {{classgames|Canvas}} so change <code>MakeColor()</code> code to <code>Class'Canvas'.static.MakeColor()</code>.

===Color operators===
[[Unreal Engine 3]] provides Provides the <code>-</code> <code>*</code> <code>+</code> operators for colors and [[Unreal Engine 2]] only provides them if extending from {{classgames|Actor}}.

<code>-</code> Substracts a color by another color e.g. <uscript>local Color BlueColor;
local Color BlackColor;

BlueColor = MakeColor( 0, 0, 255, 255 );
BlackColor = BlueColor - MakeColor( 0, 0, 255, 255 );</uscript> ''Subtracts the blue color from '''BlueColor''' and would become a black color assigned to '''BlackColor'''.''
 
<code>*</code> Multiplies a color by the scalar (i.e. [[float]]) value e.g. <uscript>local Color BlueColor;

BlueColor = MakeColor( 0, 0, 255, 255 );
BlueColor = BlueColor * 0.5f;</uscript> ''Multiplies '''BlueColor''' by half thus '''BlueColor''' will become darkblue.''
 
<code>+</code> Adds a color to a color e.g. <uscript>local Color BlueColor;
local Color PurpleColor;

BlueColor = MakeColor( 0, 0, 255, 255 );
PurpleColor = BlueColor + MakeColor( 255, 0, 0, 255 );</uscript> ''Merges '''BlueColor''' with a red color and becomes purple then assigns to '''PurpleColor'''''.

====Performance====
Because the above operators are slow it is recommend to convert them to a [[Vector]] first and then use the vector operators instead of the color operators when you are making use of the same color and same operators a lot in one function.

===Utilities===
Because of the lack of many color operations you can view a list of community made color operations at [[UnrealScript Utils]] to use in your project.
