[resolved]mouseUp works on 1, but not 2 or 3 question

#1 I think something went severely wrong when you copied in the code. You might try again.

#2 If the second and third ones aren't working, try to find out which if-statement is causing the problem. The easiest way is to put echo statements inside each if-statement. Then you can tell whether or not it is the isObject that is failing or the $this*Mounted that is failing.

#3 ok, sorry about that code, i had switched computers and it was at that time very late, but you got the idea.

so i placed some echos in, on isMOunted it returned 1, on isObject it returned zero, so I removed isObject, tho it seems very odd, since that object is declared as a behavior field and as a global variable in it own behavior.

I then placed an echo in for the dismount method. and it says for starsStar2, that on that line of code, it is a void call.

I dont get it.

function starDismountBtn::onMouseUp(%this, %mod, %worldPos, %mouseClicks)
{
	if($starsStar1Mounted == true)
		{
			echo($starsStar1Mounted);
			%this.starsStar1.dismount();
			%this.starsStar1.setLinearVelocityY(%this.gravity);
		}
				
	if($starsStar2Mounted == true)
		{
			echo($starsStar2Mounted);
			%this.starsStar2.dismount();
			%this.starsStar2.setLinearVelocityY(%this.gravity);
		}
		
	if($starsStar3Mounted == true)
		{
			echo($starsStar3Mounted);
			%this.starsStar3.dismount();
			%this.starsStar3.setLinearVelocityY(%this.gravity);
		}
	
}

#4 sorry it actually says "call to dismount in onMouseUp uses the result of a void function call.

now, i use an onUpdate to see, when to allow, use mouse events, so my on update is like this. perhaps this is where the problem is, but i am unsure why.

function starDismountBtn::onUpdate(%this)
{
		
	if($starsStar1Mounted == true)	
	{
		%this.owner.setUseMouseEvents(true);
	}
	
	if($starsStar2Mounted == true)	
	{
		%this.owner.setUseMouseEvents(true);
	}	
	
	if($starsStar3Mounted == true)
	{
		%this.owner.setUseMouseEvents(true);
	}
}

#5 Yes, I have placed this inside the function onMouseUp inside the if($starsStar2Mounted == true)...

echo(%this.starsStar2.dismount());

it says that this line is the result of a void function call. I am wondering is it the echo itself that is void or the call to dismount?


onMouseUp...

if($starsStar2Mounted == true)
		{
			echo($starsStar2Mounted);
			%this.starsStar2.dismount();
			echo(%this.starsStar2.dismount());
			%this.starsStar2.setLinearVelocityY(%this.gravity);
		}

#6 I hate to do this, but this is my entire code for the behavior, if you can please, if there is, spot the problem.
thanks so much.

if(!isObject(starDismountBtn))
{
	%template = new BehaviorTemplate(starDismountBtn);
	
	%template.friendlyName = "star dimount btn";
	%template.description = "allows star to dismount";
	%template.behaviorType = "input";
	
	%template.addBehaviorField(starsStar1, "", object, "", t2dSceneObject);
	%template.addBehaviorField(starsStar2, "", object, "", t2dSceneObject);
	%template.addBehaviorField(starsStar3, "", object, "", t2dSceneObject);

	%template.addBehaviorField(gravity, "", float, "");
	
}

function starDismountBtn::onBehaviorAdd(%this)
{
	%this.owner.enableUpdateCallback();
}

function starDismountBtn::onUpdate(%this)
{
	%this.checkIfStarHasItsStar();
}

function starDismountBtn::checkIfStarHasItsStar(%this)
{
		
	if($starsStar1Mounted == true)	
	{
		%this.owner.setUseMouseEvents(true);
	}
	
	if($starsStar2Mounted == true)	
	{
		%this.owner.setUseMouseEvents(true);
	}
	
	if($starsStar3Mounted == true)
	{
		%this.owner.setUseMouseEvents(true);
	}
}

function starDismountBtn::onMouseUp(%this, %mod, %worldPos, %mouseClicks)
{
	if($starsStar1Mounted == true)
		{
			echo($starsStar1Mounted);
			%this.starsStar1.dismount();
			%this.starsStar1.setLinearVelocityY(%this.gravity);
		}
				
	if($starsStar2Mounted == true)
		{
			echo($starsStar2Mounted);
			%this.starsStar2.dismount();
			echo(%this.starsStar2.dismount());
			%this.starsStar2.setLinearVelocityY(%this.gravity);
		}
		
	if($starsStar3Mounted == true)
		{
			echo($starsStar3Mounted);
			%this.starsStar3.dismount();
			%this.starsStar3.setLinearVelocityY(%this.gravity);
		}
	
}

#7 [THIS IS ORDERED WRONG! HOW COULD THIS HAPPEN? ANYWAY... THIS CAME AFTER YOUR POST #6.]

To make your echo statements useful, it's best to have additional data printed out with them.

Right now, your onMouseUp will either print nothing or a single "1". A bette way to determine what portions of the code are working and what portions are not working would be to change it to something like this:

function starDismountBtn::onMouseUp(%this, %mod, %worldPos, %mouseClicks)
{
  echo( "In starDismountBtn::onMouseUp." );
  echo( "  StarsStar1Mounted? " @ $starsStar1Mounted );
  echo( "  StarsStar2Mounted? " @ $starsStar2Mounted );
  echo( "  StarsStar3Mounted? " @ $starsStar3Mounted );

  if($starsStar1Mounted)
  {
    %this.starsStar1.dismount();
    %this.starsStar1.setLinearVelocityY(%this.gravity);
  }
				
  if($starsStar2Mounted)
  {
    %this.starsStar2.dismount();
    %this.starsStar2.setLinearVelocityY(%this.gravity);
  }
		
  if($starsStar3Mounted)
  {
    %this.starsStar3.dismount();
    %this.starsStar3.setLinearVelocityY(%this.gravity);
  }
}

#8 @ william,
thanks I have used those new, to me, echo techniques, much easier to spot and read, thank you.




I still have not got this to work, and I am not sure why. I placed this echo code in, it returns that "call to dismount in onMouseUp uses result of void function call. I am unsure if this echo is the problem or the echo is pointing to the problem.

if($starsStar2Mounted == true)
		{
			%this.starsStar2.dismount();
			echo(%this.starsStar2.dismount());
			%this.starsStar2.setLinearVelocityY(%this.gravity);
		}

#9 The function "dismount" doesn't return anything that echo could print out.

#10 right, but why would it be void tho? to me thats sounds negative, like i did something wrong. Beyond that, the way I have called it in an echo, is that correct, incorrect, or redundant, since it cannot return anything?

#11 If you get an error message, you did something wrong. That's what error message are for.

If you have a book on C or C++, you should research "void" in that.

#12 ok, i just was not sure if maybe my echo call was wrong.


when placing an echo, is it ok to call one like this..


echo(%this.owner.someTypeOfCommandWithBracketsAtEndForAReturn());






is that proper syntax? I Was not sure about the () at the end, inside of an echo and if that may have been the void call or if it was the actual function itself.

#13 It depends upon what "someTypeOfCommandWithParensAtEndForAReturn()" is. If it returns a value, then echo can print it out. If it doesn't return a value, echo will become confused because it has no clue what you meant for it to do with a "void".

echo( %this.owner.getPosition() );

works.

echo( %this.owner.enableUpdateCallback() );

won't.

#14 I see, thank you.


William, I am having plenty of trouble with mount().
It works fine in one behavior, but not in another. I know my code is good, as I have checked it, double checked etc. Another reason why i know the code is good, as I replaced..

%this.owner.mount();
//skipping input for mount

with say...

%this.owner.setLinearVelocity();

and it works for that. I have played with mount positions etc. Would you have any suggestions for better handling mounts?

#15 @william,
i found out the reason. I had a game file being called up for the class, that i had forgot about, it was screwing things up.

#16 @ william. please disregard. The root of my problems were that I had some game files running which were of the same class of the objects in question.

best.
