Can't use findInRange and filter?


  • Hello everyone,

    I'm trying to find a container with an extractor next to it, but it doesn't find any 😕

            if(null == thisRoom.memory.mineralContainer){
            let myExtractor = [];
            myExtractor = thisRoom.find(FIND_STRUCTURES, { filter: (a) => a.structureType == STRUCTURE_EXTRACTOR});
            if(myExtractor.length > 0){
                let mineralContainer = myExtractor[0].pos.findInRange(FIND_STRUCTURES, {filter: (a) => a.structureType == STRUCTURE_CONTAINER}, 1);
                if(mineralContainer.length > 0){
                    thisRoom.memory.mineralContainer = mineralContainer[0].id;
                }
            }else{
                thisRoom.memory.mineralContainer = null;
            }
         }

    Isn't it possible to apply filters to findInRange? or is there something else am i missing?

    Thanks!!


  • Try moving the range before the filter.

  • JBYoshi is correct.

    Looking at the docs, findInRange() takes a FIND_* constant as first argument, the range as second, and optional parameters (such as the filter) as third input.

  • Works like a charm! Thank you guys!
