Hi everybody, I have the folloing problem: There is no possiblity to pass pointers, references, parametes unsing the event function. My objective is the following: removing an Entity (a local one!) when hitting an other entity! example
void ent_1(ENTITY* temp)
{
c_move (temp, ...);
temp.emask = ENABLE_ENTITY;
temp.event = remove_temp;//here is the problem: no parameter can be passed
}
void remove_temp (HERE NO PARAMENTER POSSIBLE)
{
ent_remove (THE temp POINTER is invalid here);
}

ok i ll try out: ok it looks like that the me pointer is automatically passed, thank you superku. But an other problem arises: When the entity is removed, the local entity of the calling function becomes invalid, what to do 
void remove_temp()
{
wait(1);
ent_remove(me);//now the temp pointer of the calling function becomes invalid
}
void ent_1(ENTITY* temp)
{
temp.emask = ENABLE_ENTITY;
temp.event = remove_temp;//here is the problem: no parameter can be passed
while(1)//while(temp)
{
c_move (temp, ...);//temp becomes invalid when it is removed, invalid pointer error
wait(1);
}
}
no idea?

thanx with the pattern of txsmi it works pretty well, the code looks like that:
int remove_temp()
{
return (my.skill1 = 1);
}
void ent_move(ENTITY *temp)
{
temp.emask = ENABLE_ENTITY;
temp.event = remove_temp;
while(!temp.skill1)
{
c_move (temp, ...);
wait(1);
}
ent_remove(temp);
}
void create_ent()
{
ENTITY *temp1;
temp1 = ent_create (...);
ent_move (temp1);
}
Ok, the handing over of pointers works quite well so far, but why does lite-c not support references, I thought it would be more like C++ and supports this feature, but here it look more like C. Does lite-c support Classes?
