Hello, this is the minimum workaround I found to work, there might be a
simpler way of forcing the registration of non-literally used classes in
the GObject system.
public class Weapon : Object {
public uint damage { get; construct; }
}
int main () {
/* Force class registration here, comment this line to see the
execution failing. */
var klass = typeof(Weapon);
Type WeaponType = Type.from_name("Weapon");
Object weapon = Object.new(WeaponType, damage: 10);
GLib.message("weapon.damage = %u", (weapon as Weapon).damage);
return 0;
}
