Arg why there are so many few people to download it these days.

NICE but The keys are not making truck move 5/10

did you pressed S?

Wow! Very nice scene!

The only thing that was confusing at first was, it wasn't clear that I had to load those "combustive balls" in order to make the engine run. After a while I finally figured it out. So, it might help if you add an instruction that says something like, "You must load yellow combustive balls, which are fuel for the engine, before you can drive the truck".

Except for that minor detail, you did a great job on the scene!

Oh so it is working!

The problem I was afraid is that sometimes, a variable inside an object doesn't work right.

Thats why I need to put:

scene.my.liveA = 1000.0;
scene.livea = 0;
scene.livea = livea;
livea = scene.my.liveA;

In order to the private variable go to the memory.

Well I'm happy because it is working xD and I'l add more instructions.

very nice! 9/10 great idea, maybe you should make the rocks a little lower or not so steep hillclimbs.

Why do you do this:
scene.my.liveA = 1000.0;
scene.livea = 0;
scene.livea = livea;
livea = scene.my.liveA;

That does not make scense. Did you forget the "my" in scene.livea?

I could fix the code for you if you first explain what the problem is and what you are trying to do.
Thanks

Xray the problem is that when you use scene.my.x, the x variable becomes "universal" so it will be used by all the marbles.

With scene.x you can have different lives for the marbles, making it more dynamic.

Test it, you can put 1 marble and go through 500 life, them put another and go through 300. One will have 300 and other will have 500, but with scene.my, both will have 300.

Well scene.my.liveA = 1000.0; scene.livea = 0;... was the only way I found to each marble have his own data. Idk why but you need to put the private variable at the "2 equal sides" for that. You can see what happens if you don't do that by going to this scene that I made too.

it is broken.

I found an bug... when the life is negative and a marble is already used, it deletes. I need to make a way that the life never goes negative.

I think the problem is you are confusing Global variables with Local variables. Scene.my.x are global variables, meaning that every entity can read and write that variable. If you want to make a variable in the local scope, so that each marble has its own version of a variable that no other marble can read or write, then create the variable with an underscore character. For example, to declare a local variable, you would write "_variable1 := 3.14" (do not use quotes!) in the text area in the upper left corner of each marble's script menu. If you first select, say, 300 marbles, and then enter the code, all 300 marbles will get their own _variable1 that no other marble has access to. The underscore character ensures that the variable will get saved with the scene. If you do not use the underscore character, the variable will only work ONE TIME, and it will not be saved with the scene!

Hope this helps!

Ohhhhhhhhhhh thank you soo much! Never know about the _x! The problem is right that, I was having the problem about saving the scene with the variable. Really thanks! The next version will be better!

You're welcome!

800 downloads! Thanks everyone.
