[Exit no TimeTick] [> Obj | Obj] -> [Exit] [> Obj | > Obj] (**********************************************************) (***GRAVITY***) (**********************************************************) (Idea: Apply gravitational forces to objects that are not being moved by the player. Process them from the top of a stack of objects downward, balancing the sum of positive (downward) and negative (upward) forces. Since we're processing downward, any object determined to be moving upwards is definitely moving upwards. Such an object indicates the bottom of a sub-stack, and the next object in the stack starts the calculation over. When we reach the bottom of a (sub-)stack, the movement of the final, lowest object tells us how the whole (sub-)stack will move, so we apply that movement iteratively upwards. NOTE: Players can grip ladders really tightly, so they are only affected by stack gravity when the player is not on a ladder. ) (***STEP 1: Mark the bodies that the player is not affecting.***) [TimeTick] [stationary Balloon no FB] -> [TimeTick] [Balloon FB] [TimeTick] [stationary Crate no FB] -> [TimeTick] [Crate FB] [TimeTick] [stationary Player no Ladder no FB] -> [TimeTick] [Player FB] (***STEP 2: Begin the gravity calc at top of each stack.***) down [no FB | Upper FB] -> [ | < Upper FB Wn1] down [no FB | Downer FB] -> [ | > Downer FB W1] (***STEP 3: Iteratively apply gravity downward on stack.***) (1.
