   - Change on input: outputs a random value generated on each frame when it is activated, and the last generated value (initialized to $0$) otherwise
   - Input defines range: outputs a random value generated on each frame in the intersection between the value bounds and the range $[\min(\text{inputs}), \max(\text{inputs})]$ when the block is activated, and the last generated value (initialized to a random value within the value bounds) otherwise
