Return only one of two results?

Post by Matt »

So I find myself calling A_SpawnItemEx a lot using SXF_NOCHECKPOSITION and wanting to do further stuff with the actor spawned. This means I must get the returned actor, but the returned bool is totally useless to me.

Something similar happens with the int returned by LineAttack.

Is there a way to return only the actor, or dump the other return into a dev/null like thing so I don't have to define a new garbage int/bool in this situation?

As far as I know, no, you need to get both return values.
