Stuck and frustrated

Hello guys i am trying to block out my game but i am getting very confused about using placeholders …So at the moment i have a cube that is my player character . its a third person game and i want to add different animations for different attacks etc but how do i achieve this with placeholders … my game is nowhere near ready for the final models … so what do i do ? lol do i spend a long time creating the final models and animations or do i block out every level without even having attacks sorted ?

You use the grey mannequin the engine templates use, and get the animation starter pack from the market for free, then you have a character you can run around with and make do things…

^this.
you shouldnt be ‘making’ anything if its a placeholder. get the tutorial/starter stuff/free marketplace assets as your placeholders, and add in your own stuff when its done.
