Sims 2 Variables

This section will record all the different variables and attributes you will likely come across. You will most often be using these through the Expression primitive [prim 0x0002]. These tables are your reference to go with that wizard. However you will also find these in various other OpCodes, some without wizards. In those cases, the numeric value before the title name is the number which represents that type of variable to be placed in an appropriate Operand.

Special Variables

There are two special variables which many instructions can only operate on. You will will especially get very used to saving the previous value of the Stack Object in order to put something else in there, then putting back the original value afterwards.

General Variable Reference

Variables
0x00 My attribute 0x01 Stack Object's attribute 0x02 My (semi) attribute 0x03 My 0x04 Stack Object's 0x05 Stack Object's (semi) attribute 0x06 Global 0x07 Literal 0x08 Temp 0x09 Param 0x0A Stack Object ID 0x0B Temp (temp) 0x0C Check tree advert: Range 0x0D Stack Object's Temp	0x0E My motive 0x0F Stack Object's motive 0x10 Stack Object's slot 0x11 Stack Object’s motive (temp) 0x12 My person data 0x13 Stack Object's person data 0x14 My slot 0x15 Stack Object's definition 0x16 Stack Obj attribute (param) 0x17 room (Temp 0) 0x18 Neighbor in stack object 0x19 Local ... ...

0x02: My [semi] attribute

This is just as the attributes above, but this time the Text List (STR#) resource defining the attributes is a semi-global instead of a private string resource.

0x05: Stack Object’s [semi] attribute

See 0x02: My [semi] attribute

0x12: My person data

This gives you access to various attributes of a Sim.

hex	dec	Person Data attribute	Details
0x0000	0	Sitting?
0x0001	1	Money Amount over Head
		...
0x0008	8	Current Outfit	This is the current outfit type, e.g. 0 = Casual. This is not which outfit of that type they are wearing. It does not change if you change outfit within the type.
0x001B	27	tick counter
0x0028	40	route goal
0x0050	80	ci: Current Interaction Object ID
0x0052	82	Fatness [0-1000]	Three ranges, 0 being fat, 1000 being fit. Can be seen as part of your Sims "Personality" page in the game.
0x0067	103	ci: Current Running Object ID
0x006B	107	School Object GUID 1	These two form the upper and lower portions of the GUID for the object that is the School attended by the Sim. Setting these to Temp[0] and Temp[1] and then using the Set to Next [prim 0x001F] with Object of type GUID in temp 0/1 will give you a Stack Object that you can then run call trees against and so on.
0x006C	108	School Object GUID 2

0x13: Stack Object’s person data

See 0x12: My person data above for more details.

0x15: Stack Object’s definition

This gives you access to the various attributes of an object that you have defined in Object Data (OBJD). If you look at the RAW Data tab in 'Alphabetical' order rather than 'Categorized' order you will see the names in exactly the same order as shown in any instruction wizard.

0x19: Local

You can use local variables. If you use local variables in a BHAV you must remember to set how many. See BHAV#Declaring your stack variables for details on how to do this.

and plenty more to come
