Navigational Points

Cant figure out what im doing wrong here, if you could assist me Lax:)

Here is my Nagivational xml file;

<?xml version='1.0'?>
<Navigation>
	<World Name="TestPath">
		<Point Name="TestPath0">
			<X>885.130005</X>
			<Y>7.090000</Y>
			<Z>-471.140015</Z>
		</Point>
		<Point Name="TestPath1">
			<X>886.280029</X>
			<Y>6.200000</Y>
			<Z>-457.820007</Z>
		</Point>
		<Point Name="TestPath2">
			<X>889.119995</X>
			<Y>5.360000</Y>
			<Z>-439.929993</Z>
		</Point>
		<Point Name="TestPath3">
			<X>884.039978</X>
			<Y>4.030000</Y>
			<Z>-420.369995</Z>
		</Point>
		<Point Name="TestPath4">
			<X>881.270020</X>
			<Y>0.890000</Y>
			<Z>-393.500000</Z>
		</Point>
	</World>
</Navigation>

Here is some code im testing it with;

Code: Select all

declare filename string local EQ2Navigation.xml
	declare NearestPoint string local 
	declare world string local TestPath
	declare EndPoint string local TestPath5

	Navigation -load $&#123;filename&#125;
	
	NearestPoint&#58;Set[$&#123;Navigation.World["$&#123;world&#125;"].NearestPoint[$&#123;Me.X&#125;,$&#123;Me.Y&#125;,$&#123;Me.Z&#125;]&#125;]
	echo $&#123;world&#125;
	echo $&#123;NearestPoint&#125;
	echo $&#123;EndPoint&#125;	

	NavPath "$&#123;world&#125;" "$&#123;NearestPoint&#125;" "$&#123;EndPoint&#125;"
	
	echo $&#123;NavPath.Points&#125;

The ${NearestPoint} seems to be working as it should when I move around the recorded navpoints. However, the NavPath.Points is always returning 0. Something wrong with NavPath, and I dont know what im doing wrong.

The points are simply not connected, so there's no path from any point to another.

Code: Select all

		<Connection From="TestPath" To="TestPath1" BiDirectional="1" />

Figured out my problem. I was actually using the NavPoint -connect already, but then I found that my syntax for ${LastPoint} was incorrect. It was strange because

Code: Select all

LastPoint&#58;["$&#123;world&#125;$&#123;PointCount&#125;"]

wasnt generating an error for me, as it should have been this;

Code: Select all

LastPoint&#58;Set["$&#123;world&#125;$&#123;PointCount&#125;"]

And because it didnt generate an error, thought there was something else wrong:)

Interesting, I'll fix that
