I play with a joystick controller (Xbox controller plugged in to my computer, go to options - gameplay - gamepad mode i think) which i really like except there are addons like TTR or votans fish fillet that you can't access while using the joystick controller. Is there something I can do like bind some keys to the add ons or are the addons just not compatible?
They are just not compatible as ZOs named a lot of the files and controls on your UI differently between keyboard and gamepad mode.
Some hooks or changes in the game code aren't possiblw while in the gamepad mode as well.
You could try to use AdvancedDisableControllerUI addon to just change game fights etc. to the gamepad mode and leave the inventory and menus show like the keyboard mode. But even this won't work with many addons, sorry.
