Selling Buildings and Item Triggering help :)

#12005-08-05

Ok in my Jurassic park map, usually the new players get stuck in their gold mine from building too close to the tent(return resource) and got stuck until someone destroyed their mine/tent.

Well I think the option to sell the mine is a good idea. The mine is just a simple unit(building). How do I encorporate able to selling it?

Also Human victory is to escape to the bottom right docks. I initially placed a gate right there, so humans had to destroy it, but it didn't really hinder or help dinosaurs or humans.

So I came with an idea you need a key to open it.

First step is to make the gate invulnerable, should I with the object editor or initialization triggers?

Second how do I make it so:

If a survivor is holding a rusty key in his inventory and is in the region next to the door to null the invulnerablitiy/break the gate?

And lastly, I am almost sure I can do this on my own but, not entirely sure.

I want a dino handicap system to help the remaining dinos if one dino leaves.

I was thinking a kind of upgrade system. An example would be

1 Dino leaves and gives the 3 remaining dinos 5 gold each. now near each dino spawn/nest there is a building that holds upgrades for the dinos. They can choose which to upgrade so their loss isn't so harsh.

Or would a simple All dinos gain control of the dino that left be more helpful if they left?

Thanks in advance
