| void choose_random_tech | ( | struct research * | research | ) |
Finds and chooses (sets) a random research target from among all those available until presearch->researching != A_UNSET. Players may research more than one tech in this function. Possible reasons:

| void choose_tech | ( | struct research * | research, |
| Tech_type_id | tech | ||
| ) |
Called when a player chooses the tech they want to research (or when the server chooses it for them automatically).
This takes care of all side effects so the research target probably shouldn't be changed outside of this function (doing so has been the cause of several bugs).

Players sharing the research have got a new technology (from somewhere). 'was_discovery' is passed on to upgrade_city_extras. Logging and notification is not done here as it depends on how the tech came.
