Hi everyone. I need a couple of codes. I'm brand new to codes so I can't do it myself. Here is what I need:

1)When a trigger zone triggers, spawn a character in any place.(Character should be able to attack after spawning.)

2)When a trigger zone triggers, spawn a character in any place for a second then despawn it.(Character should be able to attack after spawning.)

3)When a trigger zone triggers, despawn a character which is in any place.(Character should be able to attack before despawning.)

4)When a trigger zone triggers, spawn an object in any place.(Including buildings.)

5)When a trigger zone triggers, spawn an object in any place for a second then despawn it.(Including buildings.)

6)When a trigger zone triggers, despawn an object which is in any place.(Including buildings.)

7)When a trigger zone triggers, show a picture on the screen for a second then disappear it.

That's what I need for now. If you can help me I will be so grateful
