ACCG involves the acceleration due to gravity of a particular object.
Usage
Command
Syntax: ACCG A(float)
Sets the acceleration due to gravity of TARG in pixels per tick per tick. In other words, the agent will gain A velocity, negative or positive, on the Y-axis per tick.
Function
Syntax: ACCG
Returns, as a float, current acceleration due to gravity of TARG, as set by the above command.
Examples
ACCG being used in the command line to make HOTS fall at 20 pixels per tick squared:
TARG HOTS ACCG 20
Make HOTS fall twice as fast:
TARG HOTS SETV va00 ACCG MULV va00 2 ACCG va00
Antigravity! Reverse the ACCG value of all agents in the world, so objects fall upward.
ENUM 0 0 0 SETV va00 ACCG NEGV va00 ACCG va00 NEXT
Equivalent in the real world
There is no equivalent of ACCG in the real world. In the real world, all objects which are affected by the same strength of gravity fall with the same acceleration, and differences due to various factors such as altitude are negligible within normal range. This was demonstrated by Galileo, apocryphally by dropping similarly-sized balls from the Leaning Tower of Pisa.
In this respect, the CEE's laws of physics corresponds more closely to Aristotle's world model, in which he postulated that objects fall earthward in direct proportion to their weights.
The reason for the common assumption that heavier things always fall faster is that heavier objects typically have less air resistance than lighter objects - that's why a feather, which is flat, falls much more slowly than a brick, which is blocky. However, on the Moon, since there is very little atmosphere, both fall at the same speed.
