init_unit (00)
| Argument | Explanation |
|---|---|
| unk | unknown purpose |
This function initializes some data structures of the unit to it's default values. It should be used as the first function called by a unit script.
wait_for_deploy (01)
Blocks the execution of the units script until the deployment phase is finished.
In the deployment phase it sets bit 31 of unit flag 1. At the end of the phase it clears the bit.
reset_call_stack (02)
Resets the units stack. Don't call this when you have to return from a function or are in a loop.
restore_ip (03)
Restores the state saved with save_ip (execution continues after the save_ip call). All events get marked as handled so unhandled events are lost.
save_ip (04)
Stores the current state of the instruction pointer (current function, position in function, number of free stack slots). Note that the stack itself is not saved!
do (05)
Begins a do-loop (pushes position of next opcode on the stack). This loop is always executed at least once.
always (06)
Usually used at the end of a do-loop. Pops from the stack and continues script execution at this position (this is usually the command following the do-statement).
while (07)
Usually used at the end of a do-loop. Pops from the stack and checks the conditional flag:
| Condition | Result |
|---|---|
| true | Continue execution at stack position |
| false | Continue execution with command after while |
