OK i have a building with a dummy abbilty called create steel. To use the abbilty you need at least 1 item Iron Ore in the inventory. the trigger removes the iron ore and puts in steel. i cant figure out the conditions for the trigger. I have one condition that says abbility being cast is equal to Create steel, so it knows its the steel mill but how do i make a condition that tells if theres the 1 iron ore in the inventory?
