How To Cut Down a Tree

there are multiple ways to cut down trees. for a knife, axe, and spear you need to do the following.
make sure you are standing on the same tile as a tree, so it shows as being straight in front 0 tiles away.
draw either your knife, axe, or spear. actually draw it and have it active in one of your hands.
then start hitting space, you will hear it chop at the tree every time you hit space. with an axe and a spear the tree will be cut down pretty fast. but with a knife this will take awhile and use up allot of energy.
you will know it when the tree is cut down, first when you hit space you'll only be cutting air, and you will then hear the tree fall and hit the ground.
With a grenade you need to:
make sure the tree is straight in front of you, but not 0 tiles away, at least 1 tile away.
if you draw a grenade in a hand and hit space you will throw it and it will hit the tree. keep doing this until the tree falls down, it may take up to 4 or 5 grenades.
after the tree is cut down you can go to its tile and hit space with an empty hand to collect wood.
if you hit space on a tree that is still standing you will collect branches.
