Deleting objects boggling me

Hi. New to Alice and the site so please forgive my pedestrian question. It's driving me batty.

I'm doing a city skyline with various planes, helicopters, ostriches flying over it. Completely simple, beginner stuff. Problem is, I can't figure out how to delete the objects when I'm done with them. So they just sit offstage (outside of lens angle) somewhere. Sometimes I use them again and when I do, I want them to come in at different points then where they are 'waiting'. So then I have to figure out were they ended up, 'fly' them around the lens angle, line them up and have them come onstage at a different place.

Is there a way to 'delete' an object after use? I'm sure this q has been asked and answered but I couldn't find it with searching.

Thanks in advance,
Blake

Make the Object either 0% opaque, or SetVisibile False, both can be found in the Objects properties section, and if u want them to fly back in at different spots, you can set up hidden objects around the air using the same method i just told you, and you can have the planes and helicopters MoveTo those objects once your done with them in preparation for the next time you need them. I hope this answers your question.

Ping: Thanks for the tips. I suppose those objects have to always exist somewhere after calling them.

yup, unfortunately, another bad thing is that you cant create objects after the program is executed, which is kind of lame imo.

Don't understand what you mean...You mean can't create new objects in the middle of execution? I'm totally new but don't understand why you would need to.

you really dont need to, but it would be nicer if you could destroy and recreate the objects at a location, for example in a first person shooter if i wanted to kill stuff and then make new ones run at me, instead i have to make the old ones invis then move back to the spot i want them to come from. just a lot of hassle
