Well, in general found out how things work. But I have 2 problems I can't solve. First, I'm using 2 of the starter pets. Bunny and Lion. They both have more than one skills as far as I can see.
$this->skills_cnt = 4;
And the required functions are also there. Nonetheless in the scroll down menu only 1 skill is showing.
My second problem, I'm using SMF + Joomla bridge. When I trained a pet or tried to use a skill and then click the return link, I land on the link
forums/index.php?action=shop;do=pets
but the correct link would be
index.php?option=com_smf&Itemid=56&action=shop;do=pets
I'm no php programmer. So I would be happy about a hint how I can fix the links problem. Perhaps I have to edit some code?
