🟦 Decrement

The Decrement block allows you to subtract a precise value from a Number type variable, providing a convenient shortcut for operations like removing life points, decreasing a counter or adjusting a balance without manual calculation.

This block simplifies arithmetic operations by automating subtraction (variable = variable - value), thus avoiding errors and speeding up flow design.

📥 Entries

• variable (Number): The targeted numeric variable, previously defined in the project.
• value (Number): The number to subtract from the variable (default: 1).

📤 Outings

• out (Stream): The output flow that activates after the decrement is successful.

💡 Example of use

Scenario: Management of life points in a game

1. The player takes damage after an enemy attack.
2. The system checks that the life points (player_pv) are greater than 0.
3. The Decrement block is called with:

• variable = player_pv (current value: 30).
• value = 5 (damage inflicted).

1. The player_pv variable changes to 25.
2. The output stream (out) triggers a check to display a message ("Damage taken!") or activate a visual effect.

⚙️ Technical Details

• Behavior: The decrement is immediate and directly modifies the target variable. No type validation is performed (make sure variable is of type Number).
• Default value: If value is not specified, the subtraction is 1.
