If the top bit of the flags is set, then the bottom two bytes of the flags become an index value. If it is not set, then the provided value is value of the parameter. If <code>flags & 1 << 0x18 != 0</code>, then the index is an expression index (EXB) and the normal value field becomes the input value for the expression. If <code>flags & 1 << 0x1e != 0</code>, then the index is a calculation preset index. Note, this is only applicable if the parameter is a float. Otherwise, if <code>flags & 1 << 0x19 != 0</code>, then the index specifies the command data type. 0 is the current frame normalized (i.e. <code>(current_frame - start_frame)/total_duration</code>), 1 and 2 are random float values between 0.0 and 1.0, 3 is an unknown string value, 4 is the command's fade in frame, and 6 is an unknown float value. Note, this only applies if the parameter is a float or a string. In all other cases, the index is a blackboard index and value of the parameter is the value of the corresponding blackboard parameter. For float parameters specifically, <code>flags >> 0x1a & 3</code> specifies the exact parameter source. 0 is a float blackboard parameter while 1, 2, or 3 are a vector3f blackboard parameter with 1, 2, and 3 being the x, y, and z components respectively.
