How to use the command 'roll' (with examples)
The ‘roll’ command allows users to simulate rolling dice. It can roll different numbers and types of dice, perform mathematical operations, and filter or modify the results in various ways. This command is especially useful for board game enthusiasts, role-playing game players, and anyone else who needs to simulate dice rolls.
Use case 1: Roll 3 6-sided dice and sum the results
Code:
roll 3d
Motivation: This use case is useful when you want to simulate rolling three 6-sided dice and calculate the sum of the results. This can be used in games that involve adding dice results together, such as Yahtzee or certain role-playing games.
Explanation:
- ‘roll’: the command itself
- ‘3d’: specifies that you want to roll three 6-sided dice
Example output:
Result: 11
Use case 2: Roll 1 8-sided die, add 3, and sum the results
Code:
roll d8 + 3
Motivation: This use case is helpful when you want to simulate rolling an 8-sided die, adding a constant value to each roll, and calculating the sum. It can be used in role-playing games to simulate various scenarios where a modifier needs to be added to the result of a die roll.
Explanation:
- ‘roll’: the command itself
- ‘d8’: specifies that you want to roll one 8-sided die
- ‘+ 3’: adds a constant value of 3 to each roll
Example output:
Result: 9
Use case 3: Roll 4 6-sided dice, keep the 3 highest results, and sum the results
Code:
roll 4d6h3
Motivation: This use case is useful when you want to simulate rolling four 6-sided dice and keeping the three highest results. It can be used in role-playing games such as Dungeons and Dragons, where players often need to make ability checks by rolling multiple dice and selecting the best rolls.
Explanation:
- ‘roll’: the command itself
- ‘4d6h3’: specifies that you want to roll four 6-sided dice and keep the three highest results
Example output:
Result: 14
Use case 4: Roll 2 12-sided dice 2 times and show every roll
Code:
roll --verbose 2{2d12}
Motivation: This use case is helpful when you want to simulate rolling two 12-sided dice for two different attempts and see each individual roll. It can be used in games that involve multiple rounds or multiple players, where each player needs to roll dice and take turns.
Explanation:
- ‘roll’: the command itself
- ‘–verbose’: displays every roll separately
- ‘2{2d12}’: specifies that you want to roll two 12-sided dice twice
Example output:
Roll 1: 5 + 9 = 14
Roll 2: 3 + 8 = 11
Use case 5: Roll 2 20-sided dice until the result is bigger than 10
Code:
roll "{{2d20>10}}"
Motivation: This use case is useful when you want to simulate rolling two 20-sided dice until the result is greater than 10. It can be used in games where a certain threshold needs to be reached for a successful outcome or in simulations that require random events until a certain condition is met.
Explanation:
- ‘roll’: the command itself
- ‘{{2d20>10}}’: specifies that you want to roll two 20-sided dice until the result is greater than 10
Example output:
Roll 1: 17, 6 - Failed
Roll 2: 12, 15 - Succeeded
Use case 6: Roll 2 5-sided dice 3 times and show the total sum
Code:
roll --sum-series {{3{2d5}}}
Motivation: This use case is helpful when you want to simulate rolling two 5-sided dice three times and calculate the total sum. It can be used in games that involve accumulating points or in scenarios where multiple rolls need to be made and the sum needs to be calculated.
Explanation:
- ‘roll’: the command itself
- ‘–sum-series’: calculates the sum of series of rolls
- ‘{{3{2d5}}’: specifies that you want to roll two 5-sided dice three times
Example output:
Roll 1: 3 + 4 = 7
Roll 2: 2 + 5 = 7
Roll 3: 5 + 4 = 9
Total sum: 23
Conclusion:
The ‘roll’ command provides a versatile tool for simulating dice rolls. It allows users to specify the number and type of dice, perform mathematical operations with the results, and even filter or modify the rolls. This makes it an invaluable resource for gamers and anyone else in need of randomized outcomes.
