[ManiaScript] ValueLineCount not working for maptype scripts

[kastun]

I discovered that MlLabel.ValueLineCount always returns -1 if the manialink is displayed in maptype context.

\Documents\ManiaPlanet\Scripts\MapTypes\ShootMania\Test.Script.txt

Code: Select all

#RequireContext CSmMapType

main() {
	ManialinkText = """
		<manialink version="1">
			<script><!--
			main() { 
				declare CMlLabel MlLabel;
				
				MlLabel = (Page.GetFirstChild("MlLabel") as CMlLabel);

				log("MlLabel line count: " ^ MlLabel.ValueLineCount);
			}
			--></script>
			<timeout>0</timeout>
			<label id="MlLabel" posn="0 0 3" sizen="150 10" halign="center" valign="center" text="Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

		</manialink>
	""";

	while(True) {
		yield;
	}
}

If the same manialink code is opended with the manialink explorer the correct result is returned.

EDIT:
If changing the text on the label with SetText() the ValueLineCount is not changed.
This is also the case if not in maptype context.

Just found out by testing again: The ValueLineCount gets only updated if you yield;.
So as workaround simply yield before you get the ValueLineCount and you will not have a problem with -1 in maptype context. EDIT: This is only working if the label is visible!

Regarding the edit of my last post:
Also here yield; after SetText() is the solution to get the updated ValueLineCount.

For reproducing create the following files.
With using this Test.Script.txt as gamemode for editing a map in shootmania you get the -1 bug.
With loading file://Media/Manialinks/test/lineCount.xml in the manialink browser you get the right value without yield.

		yield;
