If the color data being rasterized is more opaque than the color at a given pixel, then the pixel is written. Otherwise, the rasterizer ignores the pixel altogether, saving the processing required to blend the two colors. It is also used to cut off fuzzy edges of semi tranparent masks or semi transparent texures.<br /> <br /> ==Usage==<br /> <br /> &#039;&#039;&#039;alpharef&#039;&#039;&#039; [&#039;&#039;state&#039;&#039;] [name=&#039;&#039;name&#039;&#039;] &#039;&#039;[global]&#039;&#039;<br /> <br /> ===state===<br /> A [[Object scripting#Boolean|boolean]] value. If &#039;&#039;off&#039;&#039;, an object renders transparencies a full 100%, while &#039;&#039;on&#039;&#039; renders transparencies up to 80%, while the remaining 20% is cut-off and acts as fully transparent.<br /> <br /> ===name===<br /> As with most other commands, you may choose to specify the &#039;&#039;[[name]]&#039;&#039; of another object to apply the transparency rendering state to by using the optional name parameter.<br /> <br /> ===global===<br /> A command with the &#039;&#039;global&#039;&#039; argument appended will cause the object to change the transparency rendering state globally for all users who have the object in view. Without the global parameter, the object will change its state exclusively for the person who activates the trigger ([[bump]], [[activate]], [[adone]]).<br /> <br /> ==Examples==<br /> <br /> [[create]] alpharef off name=abc<br /> Creates an object named &#039;&#039;abc&#039;&#039; that renders full transparency 100%.<br /> <br /> create alpharef on<br /> Creates an object that renders transparency up to 80%, cutting off the remaining 20% and making it fully transparent.<br /> <br /> {{Build}}<br /> [[Category:Building commands]]<br /> [[Category:5.1]]</div>
