To create a slave, pass ENEMY_IMMUNE for hp in create_enemy(). tip: create_enemyg(...) is an abbreviation for create_enemy(&global.enemies, ...).
There is something like a super fancy event system for Enemies' logic rules now: logic_rule will be called with t = negative special values like EVENT_BIRTH or EVENT_DEATH on corresponding events. cool, isn't it? well those values have to be filtered out (like if(t < 0) return;) if you don't use them so they don't do strange things with your locus.
