setLinearVelocity on new t2dStaticSprite

Hi all,

Apologies for what is quite possibly a very n00b question, but hey, it's my first post :P

I'm creating sprites at runtime and adding them to my scene; I set their linear X velocity, however they are not moving. Do I need to enable their physics? If so how?

Here's my code:

%splash = new t2dStaticSprite()  
		{   
		scenegraph = SceneWindow2D.getScenegraph();  
		class = splashClass;  
          
		}; 
		%sceneGraph = SceneWindow2D.getScenegraph(); 
	
		%sceneGraph.addToScene(%splash);
	
		%splash.setPosition(%this.getPositionX(), %this.getPositionY()); 
	
		%scale = getRandom(50,60);

	
		%splash.setSize(%scale, %scale);
	
		%splash.setImageMap(splashImageMap);
		%splash.setLinearVelocityX(-100);

Any help would be awesome! Thanks in advance

    Clean your code a bit first:
    Set image map via 'imageMap' field
    Either assign scenegraph to the 'scenegraph' field OR call for scenegraph.addToScene(), the latter is better I guess.
    Size and position also can be assigned within {}.

    Default physical settings should be okay for what you are trying to do.
    Remove 'class = splashClass' and try again, most likely it is class code who prevents sprite from moving.
    Also you can getLinearVelocityX() from the object and echo it to see what's the value there.

    OK, I've tidied things up a bit.

    getLinearVelocityX() is returning the velocity I'm setting, but the sprite itself still doesn't move.

    I have had to tick "Uses Physics" on other scene objects in order to get setLinearVelocity working, is there such a function for doing so within TorqueScript?
