Using the 'playmaker UGui component' script' for UI components. If you set the FSM local float variable for a slider then change the variable name later, it won't work any more. You have to delete the script and put a new one on the slider.
So, I create a slider.
I create a float variable.
I put a FSM on it.
I put the playmakeruguicomponet script on it. the settings are 'use owner', 'set fsm variable', 'owner', 'fsm' and 'sloder-FLOAT'.
Now later I realized I misspelled the local FSM variable. I change it to 'slider-FLOAT'. Now the slider will not work. You have to remove the playmaker script 'playmakeruguicompnent' and put a new one on again and obviously redo the actions.
Edit:
Also, if you copy the slider and paste it to make 2nd slider, it won't work as well.
Also, I have not been able to get more than 1 slider working on screen at the same time. I even tried putting them on different canvases.
