Returns 1 if the specified animation action exists for the player (this only checks P1's animation data). If P1 has been given P2's animation data by a hit, SelfAnimExist will not check P2's animation data to determine whether or not a given action exists.

Format: SelfAnimExist [oper] value

Arguments:

- [oper]: =, != (other operators not valid)
- value (int): Value to compare with.

Return type: boolean (0 if false or 1 if true)

Error conditions: none

Example:

`trigger1 = SelfAnimExist != 200 ; Triggers if the player own animation data is missing action 200.`
