UI Lua API import (WAR 1.4.8)

New page

{{LuaApi|group=CircleImage}}
Sets which part of a CircleImage is drawn, as a pie-shaped arc.

<pre>
CircleImageSetFillParams(imageName, startAngle, fillAngle)
</pre>

== Arguments ==
;imageName : <code>string</code> – Name of a CircleImage window.
;startAngle : <code>number</code> – Angle in degrees where the drawn arc begins.
;fillAngle : <code>number</code> – Size of the arc in degrees. <code>360</code> draws the full circle. This is the extent of the arc, not the angle where it ends.

== Returns ==
Nothing.

== Details ==
* Both angles are converted to radians and stored. If the image's geometry already exists, it is rebuilt at once with the new arc.
* The stock UI uses it to draw a countdown ring that empties over time (see the example).

== Errors ==
* <code>Error in function call 'CircleImageSetFillParams': Window %s does not exist</code>
* <code>Error in function call 'CircleImageSetFillParams': Window %s is not a CircleImage</code>

== Example ==
From <code>ea_playerstatuswindow/source/playerwindow.lua</code>:
<pre>
-- Starts at 12 o'clock and decreases clockwise
local startFill = 360 * (1 - (PlayerWindow.KillingSpreeRemainingTime / PlayerWindow.KillingSpreeTotalTime))
CircleImageSetFillParams( "PlayerWindowKillingSpreeArc", -96 + startFill, 360 - startFill )
</pre>
