Various problems in GM6, Please help me.

1. I'm trying and trying, but sometimes, two objects appear. I'm using a "create random object" and "delete self" combo but two still show up sometimes. A little help please?

2. I want the player to be able to place an object in a room... without it disappearing right after leaving. I would like a Secret Base (Pokemon Ruby/Sapphire) style: access computer and place objects.

3. A shop. Any idea how to fix it up? You buy stuff with the points you gather.

If you don't know how, I guess my game will have a few glitches/missing ideas.

1. Ever tried "change the instance and separate object combo"

2. Make the room "persistent". It's at room settings under speed setting.

3. global.variables! Use them. Just type in "global." in front of a variable.

1. Huh?

2. Makes sense. But the player is able to place objects where he wants. With a computer to move, place, and store them.

3. Globals make the world go round. (har har) I understand, points is a varable, make global to buy stuff with. Cool.

You fixed one problem, thanks!

Change the instance. If you use that action, there is no probability for two or more random objects to be created. I used that technique in Super Mario Battle (my second game).

Hmm... so... make a 1 out of however chance the instance changes into another object? OK, makes sense. Thanks. Now about the player placing objects... just type up a code or whatever for me to copy and paste. If anyone can do that, my game will be ready to play!
