The language
The field script language in ff8 is a simple assembly language with a stack. Here is an example:
stack = []
PSHM_W 1024 # push var1024 onto the stack (stack = [var1024]) PSHN_L 6 # push number 6 onto the stack (stack = [6 ; var1024]) CAL EQ # compare the two numbers at the top of the stack, pop this numbers, and push the result (1 or 0) into the stack (stack = [1 or 0]) JPF LABEL1 # if the popped top of the stack is 0, jump to LABEL1 PSHN_L 0 # push 0 at the top of the stack (stack = [0]) POPM_W 1024 # pop the top of the stack into var1024 (stack = []) JMP LABEL2 # goto LABEL2 LABEL1 PSHN_L 1 # push 1 at the top of the stack (stack = [1]) POPM_W 1024 # pop the top of the stack into var1024 (stack = []) LABEL2 ...
In standard code, it's equivalent to:
if(var1024 == 6) {
var1024 = 0;
} else {
var1024 = 1;
}
Reading Documentation
Each Opcode's page lists all the parameters for that function in the order you would put them on the stack before the function call. The inline argument is listed separately, if the function requires one. For example, on the page for SET3, the parameters are listed like this:
- XCoord
- YCoord
- ZCoord
- SET3
Which means when you call SET3, the ZCoord is the top item on the stack, YCoord is under it, and XCoord is under that, for example
PSHN_L 402 (XCoord) PSHN_L -381 (YCoord) PSHN_L 20 (ZCoord) SET3 17 (walkmesh triangle ID)
