FS2004 XML animation script

[Jakes]

What is wrong with this script?

 <part>
      <name>tankanimate01</name>
       <AnimLength>100</AnimLength>
      <animation>
         <parameter>
            <code>
if{(A:FUEL TANK EXTERNAL2 QUANTITY, gallons) 3  &gt; }  els{ 0 }
			</code>
				<lag>50</lag>
         </parameter>
      </animation>
   </part>

What I want to do is to animate my droptank to fall. so this tiny part need to animate from 0 to 100 once the external tank reaches 3 gallons. The droptank is attached to this tiny part, then I use another script that hide the tank once it reached 2 gallons. this way you can see the tank fall, and is hidden after a few sec's.

That script really won't do anything - the format of an if statement is that the expression to evaluate goes before the if, and the two possible results afterwards:

(L:Something, bool) if{ (result for true) } els{ }

Something like this:

3 (A:FUEL TANK EXTERNAL2 QUANTITY, gallons) > if{ 100 } els{ 0 }

Animate it so that keyframe 0 is in the attached position, then 100 is fully fell away. Adjust the lag value to control how long it takes to fall.

Thank you, will try that!!

The only problem with the above is that "bool" is binary: 1 or 0
To use correctly, the units specified should be "enum" or "number."

Ooops, quite correct...

Thank you very much for the info! I am really learning a lot here!

Learning ......again

what does the * and the 2 0 1 1 4 mean in the following?

   <code>2 0 1 1 4 (A:FUEL TANK SELECTOR:1, enum) case 25 *</code>

 

[n4gix]

The star (*) is the multiplication operator, as is explained in the SDK...

What it does in this statement is take the returned value of the case (0, 1, or 2) and multiply it by 25.

This is done so that the animation will be scaled to match the keyframes used by the object in the model:

0 * 25 = frame 0
1 * 25 = frame 25
2 * 25 = frame 50

Thank you very much! I guess I have to spend more time reading the SDK's and not just jump into something
