Notes
Complex routine doing not such complex things... (while Variable ID is < 0x400 - after it's events and i can't tell yet) 1st Variable will be loaded and might be altered, depending of command ID.(math or logic). 2nd value will be used to change 1st variable value. 2nd value might be an immediate or a variable. If the command ID is an even number : 2nd value is used as an immediate If commande ID is an odd number : 2nd value is used as a 2nd variable Variable have a different length depending of their ID, could be a word or a bit. That's why this routine looks so complicated. Change the variable value depending of Command (Command are found here Event_Instructions) - 0xbe is a nullification : 1st variable become 0x00 (do not check 2nd value) - 0xb0 0xb1 : 1st Variable + 2nd value - 0xb2 0xb3 : 1st Variable - 2nd value - 0xb4 0xb5 : 1st Variable * 2nd value - 0xb6 0xb7 : 1st Variable / 2nd value - there's a check here. if 2nd value is 0x00 call 0014c958_-_0014c990 change thread (every register might change) - 0xb8 0xb9 : Reminder of 1st Variable / 2nd value - 0xba 0xbb : 1st Variable AND 2nd value - 0xbc 0xbd : 1st Variable OR 2nd value There's 2 recursive calls (via Get_Script_Variable) - first one will clear variable 0x00 - second one depend of 1st variable ID - If >= 0x3c0 (propositions/job - events ?) - depends from where this routine were called - Else : returns variable 0x1fc value - If = 0x00 : go on - If not : check some variable ID and might abort routine Store the new Variable value on Variable pointer
