Since the SATSAT andand EAT EAT files are identical in structure it was possible to create one tool to edit both these files are identical in structure it was possible to create one tool to edit both these

file types. The reason the de!elopers created separate file types (although identical in structure) was

because there are often times that we want our proectiles to ha!e different boundaries than the player

mo!ement. Ja!ing separated boundaries for each file type gi!es us more options and a more realistic feel

of how obects and characters interact in the ; en!ironment.

'asically the EAT file determines the boundaries of where bullets& grenades& and other proectiles like

arrows hit. Also the EAT file determines where falling obects stop falling& like when we shoot a spinel from

up high and it falls down to the ground. Another feature of the EAT file is to change the reaction type of the

en!ironment to the proectiles. For instance& we can use the EAT file to make wet looking footsteps for

weather or use the EAT file to make the bullets appear as though they are hitting a water surface.

5f we are creating EAT data from scratch (say when we are creating a new room)& sometimes the easiest

method is to create teh SAT data first& and then simply copy the SAT data and fine tune it. +sually EAT

data follows the same positions as SAT data with some slight !ariations depending on the scenario.
