Featured Digital Mechanic:
Luck
Just like in desktop games, luck can be a powerful mechanic in all types of digital games.
Explore random number generator (RNG) wotj us below!
Let's explore luck through a digital mechanic...
01 Build an RNG
Here we will take you through some ways to explore luck mechanic through random number generator. Check out our step-by-step guide below!
WHAT WE ARE BUILDING:
A functioning RNG that can simplify parsing random numbers vs just using a generic rand function. A class that handles all your random number queries with simple commands vs manually asking for them each time. Use this to generate a loot table system to create random drops based on %s
- Open GDevelop and click on "Create a New Project."
- Choose any template or select "Empty Project" to start from scratch.
- In the project dashboard, you should have a default scene.
- If it’s not there, click on the "+" icon next to Scenes and select "Add a Scene."
- Name the scene if needed.
- Click on the "Objects" tab on the right and then click "+ Add a new object."
- Choose "Text" from the list of object types.
- Name your text object, such as RandomText, and adjust the text size, font, and position as necessary.
- Drag and drop the text object onto your scene to place it.
- Switch to the Events tab at the top of the screen to begin adding logic to your game.
- Click on "Add a new event" and select the event to trigger the random number generation. For simplicity, we can use a "Key Press" event to trigger the action:
- In the Conditions section, click on "Add a condition."
- Search for Key Pressed and select it.
- Set the key, for example, Spacebar.
- In the Actions section of the same event, click on "Add an Action."
- In the search bar, type Do = RandomInRange and select the appropriate action.
- Set the action to change the text of the RandomText object:
- Select the Modify the text of an object action.
- Choose RandomText as the object.
- In the text field, write the expression: ToString(RandomInRange(1, 100))
- This will generate a random number between 1 and 100 and convert it to text format so that it can be displayed.
- Click on the play icon to preview the scene.
- When you press the spacebar, the text object should update to display a new random number each time.
- You can change the range of the random number by adjusting the parameters in RandomInRange(1, 100).
- You can also trigger the random number generation with other events, like clicking a button or after a certain amount of time passes.
