Memory leak? bindCmd in a behavior returns junk data

Hi all,
Use the following code below as a behavior:
Create a new project and scene, and assign this behavior to a sprite. Press the space and z keys, and open the console. After pressing space, I do not get any data, but if I use redirect(), I get junk data.
Use the following code below as a behavior:
if (!isObject(fishBehavior))
{
%template = new BehaviorTemplate(fishBehavior);
%template.friendlyName = "Fish Behavior";
%template.behaviorType = "Player Behavior";
%template.addBehaviorField(yVelocity, "The object's vertical speed", float, 5.0);
}
function fishBehavior::onLevelLoaded(%this)
{
//moveMap is already defined in another place, and function call does work
moveMap.bindCmd(keyboard, "space", "fishBehavior.jump(1);", "");
moveMap.bindCmd(keyboard, "z", "redirect(1);", "");
}
function fishBehavior::jump(%value)
{
//line below gives me junk data
echo("yVelocity is" @ %this.yVelocity);
}
function redirect(%value)
{
fishBehavior.jump(%value);
}Create a new project and scene, and assign this behavior to a sprite. Press the space and z keys, and open the console. After pressing space, I do not get any data, but if I use redirect(), I get junk data.

It seems you're calling jump() on a null object.

So, to accomplish what you need, for *ALL* class methods (className::methodName) the first parameter should be %this. If you omit it, like you did on line 18, %value would be assigned the data that should be in %this.
So Timi's solution should work barring any other errors.

Here's the deal... TorqueScript doesn't have a concept of "this" like a real object oriented language does.So, to accomplish what you need, for *ALL* class methods (className::methodName) the first parameter should be %this. If you omit it, like you did on line 18, %value would be assigned the data that should be in %this.
So Timi's solution should work barring any other errors.

function fishBehavior::jump(%this, %value) { //line below gives me junk data echo("yVelocity is" @ %this.yVelocity); }I'm really new to Torque, this is just going off of the shooter tutorial. This is untested; simply a guess.I'd need to look into the debugging to understand why it's specifically not working. I've got some really strange fixes for my game because of %this.
