Hi i am trying to make a warrior cat game and need help with it. I do not know how to make the cats fight,hunt,eat,drink. I only can make them move. This is the description: You are a kittypet and have stumbled across Shadowclan. You ask to join but to prove your worthy you must fight the leader Darkstar (cannot figure out how to do this) Then you must hunt for 3 animals (again need help with this) after that you can choose your apprentice name (one of the things i can do) Once you are in the clan you have to talk to certain cats that will give you missions to do. These will include: rescuing a kit, taking moss to the elders, going to gatherings ect. ( would need help with this too) Every time you complete a mission you get xp (experience points) you get 10 of these each time you complete a mission when you get 50 or 100 you recieve your warrior name. Then the same night you wander into the dark forest in your dreams. You find out that the darkforest (a ledgend among clans) is plotting to again attempt to wipe out the clans so a descendent of tigerstar can rule the forest. You have to find three strong enough warriors from the clans and travel to a place far away. When you get there with the others you have to defeat all of the darkforest ( they have managed to recruit kittypets and turned them into powerful warriors) If you defeat them you go home and the game ends. I would need help from the start to the finish so if anyone knows please help me! If i finish i will try and give credit to those who helped. Please ask others to help too!
