if i have multiple copies of the same object lets say 100+ lets call it entity_a. if i tell entity_a to check entity_a`s xyz position will it check the location of all its clone objects within a single frame? and if so how fast will this be for the average computer, and will the object check its own position?ty

I don't see how, Unless you have the same action applied to entity_a
and all it's clones.

ya its the same exact thing with the same model and script attached to it

If you are making clones by script (not in wed) try to use define and var.
f.e. define number,skill1; var var_number;

while(1)
{
if(var_number <= 100)
{var_number +=1; you = ent_create....; you.number = var_number;}
else{break;}
wait(1);
}
then
if(entity_a.number == 88){show entity_a position;}

This is what You want or I don't understand something?
