Funciton not support

when i add some event to animation ,but some event not work ,it says NOT SUPPORT,WHY?how to fix it?

 

Are these both on the same character? If not, check the OnTrigger function in the character's script. Try to make the parameter list match the function on the working character. On the broken character, if you click on the event marker and select a new function, you probably won't have the option to choose OnTrigger again until its parameters are compatible with animation events.
