Thank you Samuli.
And how to cast my type Object with the same type of WD_THIS when I am in WD_ASSIST ?
Because, the interest is to use all the methods of WD_THIS in WD_ASSIST ...
Actually, in WD_ASSIT, the type of WD_THIS is not known :/
*** EDIT:
The goal is to use essentially the methods like :
- wd_this->fire_to_yyyyy_plg( ).
- wd_this->fire_to_xxxxx_plg( ).
ect ...
