This is a basic framework to get you started... not sure how you are getting the opportunity ID, but hopefully this helps.

 

trigger UpdateCustomObject (before insert, before update){

 

   for(CustomObject__c c: trigger.new){

      if (c.RecordType == TheRecTypeICareAbout){

         c.OpportunityLookup__c = theOpportunity.id;

      }

   }

 

}
