Creating a Double Jump System! How to Make a Simulator in Roblox Episode 11

New Section

In this section, the creator introduces the topic of creating a double jump system in Roblox and encourages viewers to engage with the video content.

Understanding Jump Properties

• Explains the significance of character jump height and jump power properties in Roblox affecting player jumps.

• Differentiates between character jump height (determines jump height in studs) and jump power (applies upward force).

• Acknowledges uncertainty regarding significant differences between jump power and jump height but emphasizes setting character use jump power to enabled.

Scripting Initialization

• Guides on creating a local script named "Jumping" within the starter player script.

• Establishes variables for players, user input service, replicated storage service, remotes, player, character, humanoid, used jumps, max jumps, and can jump.

New Section

This part delves into event handling for player jumping actions and setting up functions to manage character states during gameplay.

Event Handling for Jumping

• Introduces variables used jumps set to zero, max jumps set to 2 initially, and can jump set to false.

• Utilizes user input service's "jumprequest" event for detecting when a player intends to jump via spacebar press.

Character State Management

• Defines a function "character added" updating variables upon character respawn like resetting used jumps and setting can jump to false.

Jumping System Implementation

In this section, the speaker discusses the implementation of a jumping system in a game development context.

Implementing Jump Functionality

• Implement a slight delay between player jumps by using task.weight 0.2 to enhance player experience.

• Utilize task.weight to prevent players from rapidly consuming all jumps by pressing spacebar quickly.

Connecting Functions

• Call the jump function by adding an if statement below the function creation.

• Connect it above the user input service.jumper Quest.

• Ensure character added event is triggered for new players joining the game.

• Explain the necessity of listening to character added events despite initial loading constraints in Roblox games.

• Clarify why an if statement is crucial for executing functions upon player entry.

Jump Function Logic

• Create a jump function that restricts jumping when conditions are not met and updates jump counts accordingly.

• Set humanoid state to jumping and manage jump cooldown effectively.

• Connect jump request event to the jump function for seamless gameplay integration and testing purposes.

• Verify functionality by testing jumping mechanics in-game with spacebar input detection.

Configuring Jump Abilities

This segment delves into configuring player's jump abilities and setting up associated data structures.

Setting Up Jump Configuration

• Define a jumps configuration module within replicated storage to manage extra jumps and their costs in-game shop.

• Assign values based on additional jumps available and corresponding costs from shop items.

• Establish player data structure within replicated storage to track unlocked jumps, starting with default double jump capability upon game entry.

• Initialize default value for extra jumps as one, enabling double jumping functionality immediately.

New Section

In this section, the speaker discusses setting up a module script and a remote event within the server script service to create a jump shop functionality in the game.

Setting Up Module Script and Remote Event

• Adding a new module script named "jumps shop" inside the server script service.

• Creating a remote event named "purchase jump" in the replicated storage remotes folder.

• Initializing variables like player service, replicated storage, server script service, remotes, player data manager, and jumps config within the module script.

New Section

This part focuses on creating functions within the module script to handle purchasing jumps by players and ensuring they can afford it based on their clicks.

Handling Jump Purchases

• Defining a function jumps shop.purchase jump(player) to process jump purchases.

• Checking if the player can afford the next jump based on their clicks.

• Returning messages like "cannot afford" or "profile not found" based on purchase conditions.

New Section

Drawing parallels with previous system development, this segment emphasizes returning specific strings for debugging purposes while implementing jump purchases successfully.

Debugging System Functionality

• Similarity drawn between current function return messages and those used in rebirth system development for debugging ease.

• Ensuring successful purchase updates player's click count and jump properties accordingly.

• Notifying players of successful purchases through firing remote events.

New Section

The focus shifts towards updating client-side variables upon purchasing jumps and creating debug commands for testing system functionality.

Updating Client-Side Variables

• Updating client-side variable max jumps upon purchasing additional jumps.

• Introducing debug command debug jumps to test jump shop functionality via server scripts.

Script Configuration and Testing

In this section, the speaker discusses script configuration steps and testing procedures for a jump feature in a game.

Configuring Jump Feature

• Ensure to add dot config to jumpsconfig when creating the next jump price variable.

• Test the functionality by adjusting player clicks and running the debug jumps command.

Testing Jump Functionality

• Verify that the jump feature works by purchasing jumps with varying balances.

• Close unnecessary tabs related to commands and configurations once testing is complete.

GUI Design and Implementation

This part focuses on designing and implementing GUI elements for displaying jump information in the game.

Designing GUI Elements

• Create a new screen named "jumps" inside the star GUI for displaying jump-related information.

• Set appropriate scaling, positioning, font, and text color for the text label displaying jump details.

Finalizing GUI Settings

• Adjust GUI enable settings to hide it from view during gameplay.

• Configure variables in the jumping local script related to GUI elements for further functionality.

Updating GUI During Gameplay

This segment covers updating the GUI dynamically during gameplay based on player actions.

Modifying GUI Content

• Update text labels within the GUI when players perform jumps in-game.

• Modify text transparency and color based on player actions to enhance user experience.

Implementing Tween Effects

• Create tweens to animate changes in GUI elements such as making labels invisible after specific actions.

Setting Up Double Jump System

In this section, the focus is on setting up a double jump system in a game using Roblox scripting.

Setting Conditions for Double Jump

• The new state triggers when the player lands, resetting the use jumps variable.

Modifying GUI Elements

• When the max jumps are reached, set GUI elements:

• Enable gui

• Set jumps text transparency to zero

• Modify text color to red (255,0,0)

• Call tween play

Visual Feedback Implementation

• Change label color to red and gradually fade it when all jumps are used.

• Test results show successful implementation of visual feedback.

Adjusting Player's Attributes

This part focuses on modifying player attributes like jump power and walk speed to enhance gameplay dynamics.

Enhancing Jump Power and Walk Speed

• Consider adjusting jump power and walk speed during jumping phases for improved gameplay experience.

• Observations from other games suggest increased speed and jump height after initial jump.

Setting Default Values

• Define static variables for default jump power (50) and walk speed (16).

• Create variables for modified jump power (100) and walk speed (50).

Implementing Enhanced Movement Mechanics

Implementing changes in player attributes to reflect enhanced movement mechanics during gameplay.

Applying Attribute Changes

• Set humanoid.jump power and walk speed to default values upon character addition.

• Adjust humanoid.jump power and walk speed during jumping phases for enhanced movement capabilities.

Refining Visual Presentation

• Cancel ongoing tweens before enabling GUI elements to ensure proper display of labels.

• Ensure smooth transition of label appearance by managing tween services effectively.
