Minecraft-Style Block Placement System in Roblox Studio
Block-building is a popular mechanic in many games, including the iconic Minecraft. In this video tutorial, the creator demonstrates how to replicate a similar block placement system in Roblox. The tutorial covers rendering, previewing, server-side block placement, and exploit prevention. Let’s dive into the details of this fascinating process.
Rendering and Preview
The tutorial begins with a simple three-by-three cube block, which is then anchored and moved to ReplicatedStorage for accessibility by both the client and server. A local script called “ClientPlacer” is created to handle the rendering and preview of the block. The script utilizes various services such as UserInputService and RunService to create a translucent preview of the block at the mouse’s 3D position.
Raycasting and Server-Side Placement
The video delves into the process of converting the 2D mouse location into a 3D position using the camera. This is achieved by projecting the mouse’s 2D coordinates into 3D space, resulting in a unit ray with an origin and direction. The unit ray is then cast into the game world to determine the placement position of the block. The server is involved in the placement process through the use of a remote event called “PlaceBlock”.
Exploit Security and Validation
To prevent exploits and limit the distance at which players can place blocks, a module script called “PlacementValidator” is introduced. This script calculates the distance between the player and the desired block placement position, ensuring that the block is placed within a specified maximum distance. This security measure adds an extra layer of protection to the block placement system.
Future Developments
The creator hints at future videos where they plan to implement a grid system for more precise block placement, similar to the mechanics in Minecraft. Additionally, they mention a forthcoming series focused on building a game with data-saving features, expanding the scope of the project and showcasing their expertise in game development.
Overall, the tutorial provides a comprehensive overview of creating a Minecraft-style block placement system in Roblox Studio. The step-by-step explanation and practical demonstrations make it an engaging and informative resource for game developers and enthusiasts.
