Is there a way to use a list in a certain way in an if/else statement (see post)

Ok i am trying to build a flight simulator but i am stuck. Is there a way to use an object list for a if statement

*- the list of object the plane can collide with

Boolean Function world.collision

parameter collisionObject

If plane within .1 of collisionObject
Return True
Else
Return False

Method

world.collide

Parameters - collisionObject

If collisionObject == world.CollisionObjects*
BlowUp
Else
do nothing

the problem is when ever i drag the list in, it asks for the first, last, a random, or ith number.
How do i get them all??

In Alice, there are two commands that deal directly with lists: For All In Order, and For All Together. These are located at the bottom of the method editor. Drag "For All Together" into the method editor, and then select the world.CollisionObjects list. Now the if/else statement should be placed inside the For All Together. The if/else statement should now be changed to look like the following

I also put the entire thing in a loop, because you probably want it to test all the time.

I hope this helped!
