Virtual attributes

What they are and how to use virtual attributes

  • Virtual attributes are a way to use methods (get and set) as attributes through a precompiler.

⚠️ Remember that a script with many virtual attributes can cause a longer compilation time, since there is a precompiler that interprets and tranforms your "attribute" into the original method before compiling your script ⚠️

With virtual attributes:​

Example​

  • Note that the number of characters has decreased considerably.
public class YourClass extends Component {

    public int value = 10; // select from properties
    
    public void repeat() {
        
        myObject.position.x = value;
        myObject.position.y = value;
        myObject.position.z = value;

    }    

}

Without virtual attributes:​

Example​

  • Note that the number of characters has increased considerably.

public class YourClass extends Component {
    
    public int value = 10; // select from properties
    
    public void repeat() {
        
        myObject.getPosition().setX(value);
        myObject.getPosition().setY(value);
        myObject.getPosition().setZ(value);

    }    
    
}

You can also use virtual attributes in vectors​

Example​

  • Note that in the repeat function it is not necessary to call the methods of the operations.
public class YourClass extends Component {
    
    private Vector3 vector1 = new Vector3(1, 1, 1);
    private Vector3 vector2 = new Vector3(2, 2, 2);
    
    public void start() {

        // assigning values with virtual attributes
        vector1.x = 1; // the same as vector1.setX(1);
        vector1.y = 1; // the same as vector1.setY(1);
        vector1.z = 1; // the same as vector1.setZ(1);
        
    }
    
    public void repeat() {
        
        // the same as vector1 = vector1.sumLocal(vector2);
        vector1 += vector2;
        
        // the same as vector1 = vector1.subLocal(vector2);
        vector1 -= vector2;

        // the same as vector1 = vector1.mulLocal(vector2);
        vector1 *= vector2;
        
        // the same as vector1 = vector1.divLocal(vector2);
        vector1 /= vector2;
        
    }    
    
}

⚠️ If the use of virtual attributes presents some kind of error just use the methods normally ⚠️
