HOW do i tranfer energy from a creep to all extensions

[ArisingSun]

My problem is, is that it transfers it to only one extension
extension[0]

You need to find structures which need energy. Something like the code below.

    structures = creep.room.find(FIND_MY_STRUCTURES, {
        filter: function (object) {
            return object.energy < object.energyCapacity;;
        }
    });

    if (ERR_NOT_IN_RANGE === creep.transferEnergy(structures[0])) {
        creep.moveTo(structures[0]);
    }
