My responses are not in a harsh tone. I have been a member of there forums for quite awhile now and always try to help. I was responding to raven's post since the way he is offering is the inefficient way of coding what you want. And I was proposing to raven, instead of telling you step by step how to do everything, just to give you the basic information to get you on the right path. And if you know java or any other coding language, you're taking a step backwards in progress if you're focusing on Alice.

Lastly, creating the object variable under the worlds properties and making it a list that contains all use objects you want detection to occur on is one of the more efficient ways of doing collision in Alice with multiple objects. Using that variable to be called in a collision method would be a good route to go. I have to assume you're not proficient in the English language, so you may not understand the tone of what I am writing as being helpful, but that's what it is.
