| bool execute_orders | ( | struct unit * | punit, |
| const bool | fresh | ||
| ) |
Executes a unit's orders stored in punit->orders.
The unit is put on idle if an action fails or if "patrol" is set and an enemy unit is encountered.
The return value will be TRUE if the unit lives, FALSE otherwise. (This function used to return a goto_result enumeration, declared in gotohand.h. But this enumeration was never checked by the caller and just lead to confusion. All the caller really needs to know is if the unit lived or died; everything else is handled internally within execute_orders.)
If the orders are repeating the loop starts over at the beginning once it completes. To avoid infinite loops on railroad we stop for this turn when the unit is back where it started, even if it have moves left.
A unit will attack under orders only on its final action.
The fresh parameter is true if the order execution happens because the orders just were received.

If role_tech is given, then we look at all units with this role whose requirements are met by any player, and return a random one. This can be used to give a unit to barbarians taken from the set of most advanced units researched by the 'real' players.

After a battle, after diplomatic aggression and after surviving trireme loss chance, this routine is called to decide whether or not the unit should become more experienced.
There is a specified chance for it to happen, (+50% if player got SUNTZU) the chances are specified in the units.ruleset file.

When in civil war or an alliance breaks there will potentially be units from both sides coexisting on the same squares.
This routine resolves this by first bouncing off non-allied units from their cities, then by bouncing both players' units in now illegal multiowner stacks. To avoid drowning due to removal of transports, we bounce everyone (including third parties' units) from ocean tiles.
