hey guys, Simon again: i have a Problem with removing a sprite entity in its own Action:
void act_some();
void ev_event();
void main(){
you = ent_create("file.tga", nullvector, act_some);
your.skill1 = "something";
}
void act_some(){
my.emask = ENABLE_SCAN;
my.event = ev_event;
}
void ev_event(){
if(Event_type == EVENT_SCAN)
ent_remove(me);
}
//just a part of my code - the true one is bigger
game starts, works fine, until the ent_remove then scknex engine says: "Invalid call in Event ev_event". thanksfor your help! :-) answers could also be in Germany (would be better)

thank you for the reply:
i don't really understand your first post.
and to the second:
i tried it to put an wait(-5) after the ent_remove, same fail.
i Need this scan Event, so i can't put it into the Action...

Reason and solution are already in the manual (excuse the German quote): Die Eventfunktion selbst sollte einfach sein. Normalerweise sollte sie keine Informationen an die Main-Funktion der Entity übermitteln - sie sollte keine Anweisungen ausführen, die wiederum selbst Events auslösen, Entities verschieben oder sonst irgendetwas im Level verändern können. Anweisungen wie c_move, ent_create, ptr_remove, c_trace etc. dürfen also nicht durchgeführt werden. Sollte dies nämlich der Fall sein, können alle möglichen unschönen Dinge passieren: etwa dass zwei Entities bis ins Unendliche gegenseitg ihren Event auslösen (in diesem Falle würde das Game einfrieren). Muß die Eventfunktion aus irgendeinem Grund solche 'kritischen Anweisungen' durchführen, müssen diesen, um sie aufs nächste Frame hin zu verzögern ein wait(1) vorangestellt sein, dann ist es sicher.

OH MY GOD!
thank you very much, it works now perfectly!
I'm so glad you helped me!
but one more question: why can't i remove the entity in a Action?

ent_remove should ALWAYS be the LAST FUNCTION played by your event.  ent_remove SHOULD NOT AT ALL be called in an event! Event functions are actually executed during the engine function that caused the event, like a c_move, c_scan, or c_trace instruction of another entity. The event function itself should be simple. It normally should only transfer information to the entities' main function - it shouldn't perform instructions that can trigger events itself, displace entities, or change anything else in the level. Thus instructions like c_move, ent_create, ent_remove, c_trace etc. must not be performed
Always learn from history, to be sure you make the same mistakes again...

If you want to use a loop for your entity the following pattern has proven to work just fine for me:
void my_event()
{
if(...) my.skill20 = 0;
}
action my_action()
{
...
my.skill20 = 1;
while(my.skill20)
{
do sth;
wait(1);
}
ptr_remove(me);
}
All code which is more complex than setting a few values should be delegated to your main loop like that.
