need help in changing behavior value during the game

by Ghonium · in iTorque 2D · 01/09/2012 (10:40 am) · 5 replies

hello
please if some one can help me

I have a behavior called PlayerControlsBehavior
it have a template

%template.addBehaviorField(acceleration, "Forward acceleration (world units per second)", float, 2.0);

during the game on play I want when I touch the power speed button to change acceleration of the player from 2 to 10
function speedButton::onTouchDown(%this, %touchID, %worldPos)
{
   echo("Finger " @ %touchID @ " touched the thing at " @ %worldPos);


       //On touch speed button
       if($item[1] > 0) //if i have  power
         {
         //remove 1 power from item
         $item[1] -= 1;
    	 speedQuantityGui.setValue($item[1]);
    	 SaveItems();
    	 speedButton.Visible = 0;
    	 schedule(3000, 0, "ShowSpeed"); 
    	 speedme();
         
// I want to change the behavior acceleration here from 2 to 10  to give the player speed 

         }

is this possible to change the behavior acceleration value during the game?

sure, you can access it simply through .acceleration on the variable that holds the behavior.

The featureDemo has the timerShoots behavior for example where the projectile is cloned like this.

If you talk about the value on the template itself then no, thats the 'blueprint'. You would ahve to use a global variable to store the 'current to be used' acceleration and make all new objects that use this behavior read that global value and change their acceleration to it

thanks for the replay
I will check the featureDemo

actually all what I need to change the speed of the player if I touch the button of speed

and im still on learning as beginner

In that case all you need is a variable holding the behavior lets say %theBehavior and then you can use

%theBehavior.acceleration = 10

or whatever value you want :)

I solve it by adding global variable that will change
%this.acceleration on the behavior it self
I feel there is better solution that what i did but I dont know
still beginner
// A timer will start and on its on zero sec it will start ShowSpeed function
    	 schedule(3000, 0, "ShowSpeed"); 
    	 $myChickenSpeed = 1;

function MyChickenControlsBehavior::onUpdate(%this)
{
	//use this if I press speed button
	if($myChickenSpeed == 1)
	{
		%this.acceleration = 20;
	}
	//Acceleration will back to default after speed time done
	if($myChickenSpeed == 0)
	{
		%this.acceleration = 8;
	}
	
   %this.owner.setImpulseForcePolar(%this.owner.rotation, (%this.up - %this.down) * %this.acceleration);
	%this.owner.setAngularVelocity((%this.right - %this.left) * %this.turnSpeed);
}

I cant think of better solution :)
