Grouping objects

hi.....

I was wondering how to group items, i have made a number of cones that the player has to avoid whilst driving, they are numbered 1 - 4.
What i wish to know is how to make one rule for all the cones instead of having to specify what each cone is suposed to do when the car runs over it.

All the cones do the same thing but as i have 4 cones then i have had to put the same code 4 times, is there a more efficient way?

Cheers.

Hi -
It sounds as though you want to write a world-level method for your cones. If each cone does the same thing when the user drives over it then a single method is definitely in order.

You can do this by selecting the World in your Object Tree and then clicking on the create new method button in the Details view area. You could pass each cone object as a parameter to this new world-level method if you wanted something different to happen when one of the cones was hit.

If you have the manual they give several examples of how to do this beginning in chapter 4. It is rather easy to do.

Good luck and I hope this helps

Hi thanks for replying to me so quick.....

I dont have the munual unfortunatly

I kinda understand what your saying and i tried what u said but im still confused when it comes to these things and not sure what else i have to do.

What do i set the parameter as, then how do i tell alice that the parameter represents all of the cones i put down?

Gonna keep playing around with it see if i can get anywhere.

Thanks for any help you can give me

It would probably be simpler and quicker if I just sent you the code to do it. If you send me the world file (.a2w) I will return it with a method attached that you then can edit, modify, etc. You can also view/play with it to increase your knowledge in using Alice.

Good luck

I received your driving project. I added a new method, ConeDown, which receives an object as a parameter. I placed numerous comments in the code I am returning to you in hopes it helps you understand how it now funtions. Note that I named the returned file project1.a2w so that you do not overwrite your original work when you download it.

Good luck

That's a great idea for applying the same methods to many objects of the same type.

My problem is, I wish to aggregate a several objects into one, with its own internal methods and properties, specifically I want to take basic objects from the gallery (square, cone, fences) and group them into an object called a cell, that I can import as one item.

Basically, I want to turn classes into sub-parts of a new object that can be inserted repeatedly. Is the only place to create subparts in one of the threeD editors?
