I am trying to modify some code in .Net Reflector for an Android game and could use some assistance as I am still learning. As you can see in the attached screenshot the sub I am trying to edit is called 'DealDamage'. I would like to make the critAttack boolean always true, AimType always to be head (0) and no damage taken. Below is the section I believe needs to be edited with my notes added.
