Mod takeover

This modification adds the command /takeover which allows users (or only admins and mods) to make the chatbot say things.
Open lib/class/customAJAXChat.php
Before the last } add the following code:

// Add custom commands
function parseCustomCommands($text, $textParts) {
    switch($textParts[0]) {
        case '/takeover':
        $this->insertChatBotMessage( $this->getChannel(), $text );
        return true;
        default:
        return false;
    }
}

Now open js/custom.js and add this to the end of the file:

ajaxChat.replaceCustomCommands = function(text, textParts) {
	switch(textParts[0]) {
		case '/takeover':
		text=text.replace('/takeover', ' ');
		return '<span class="chatBotMessage">' + text + '</span>';
		default:
		return text;
	}
}

This will give all users the ability to use the /takeover command.

If you want to only allow this command for administrators and moderators, you should put the following in customAJAXChat.php instead of the first part of the code provided above. Notice that there is an added "if" statement:

function parseCustomCommands($text, $textParts) {
	if($this->getUserRole() == AJAX_CHAT_ADMIN || $this->getUserRole() == AJAX_CHAT_MODERATOR) {
		switch($textParts[0]) {
			case '/takeover':
			$this->insertChatBotMessage( $this->getChannel(), $text );
			return true;
			default:
			return false;
		}
	}
}
