Random
| Type | Script block |
| Collider | None |
| Folder | Math |
| Ports | |
|---|---|
| Inputs | Min Max |
| Outputs | Random |
Notes
- Port inputs default to 0 and 1 respectively.
- The Min input is included while the Max input is excluded, meaning: if the min and max inputs are 0 and 5 respectively, it may generate a number within 0 to 5, possibly 0, but never 5.
- The random block will generate a new value every time it is executed. To reuse the same random value, it should be stored in a variable.
- Note that the output would be in decimal. To avoid this use a rounding operation, ideally floor and secondarily round. Ceiling also works but is scarcely used.
- The random block behaves inconsistently when used with wire splits:
Examples
Either generate -1 or 1.
Output a random integer with equal probability.
