I would like input on different checks please

1- Player Character vs Player Character- PC searching the other PC for hidden devices.. what would be rolled?

2- Player Character vs NON Player Character- NPC searching PC for hidden devices.. what would be rolled?

3- Player Character vs Player Character- shooting each other.. what would be rolled?

4- Player Character vs Player Character- One PC trying to talk the other PC into doing something .. what would be rolled?

We are just kind of confused on some rolls and cant seem to find examples... thank everyone so very much

Why are PCs doing anything to one another against each other's will?

In the case of the NPC, the default would be an opposed roll Perception vs. Stealth. It's discussed under the Stealth skill write up.

He is a spy so we are going to search him one way or the other!

so would it be yellow/green dice vs other yellow/green dice? or do we change the other persons to the negative equivalent?

Ok combat would be the same as always regardless. The rest are opposed checks and that's spelled out how to assemble an opposed check in the dice mechanics. I would never have PCs rolling any social checks against one another though.

Opposed checks are explained beginning on page 24 EoE CRB.
