Unity Grid Placement 3D - Plcement, Roate, Delete, Visualize

Overview

This project is a comprehensive implementation of a 3D grid placement system. It provides dynamic and precise placement of objects within a 3D space, leveraging a grid-based system to ensure accuracy and alignment. This tool can be particularly useful in game development, architectural visualization, and any application requiring spatial organization.

Features

• 3D Grid Visualization: A clear and adjustable 3D grid that provides a reference for object placement.
• Object Placement, Rotation, and Deletion: Manage grid objects through placement, directional rotation, and deletion.
• Visual Feedback: Provides visual feedback to indicate if an object can be placed.

Installation

1. Clone the repository:

   git clone https://github.com/Litt1eStar/Grid-Placement-3d-Completed-Version.git

2. Open the project in Unity: Ensure you are using Unity version 2020.3 or later for compatibility.
3. Load the main scene: Open the Playground.unity file to get started.

Usage

1. Grid Initialization: The grid is initialized automatically when the scene loads. Configure grid size and spacing through the GameManager script.
2. Placing Objects: Select an object from the object palette and click on the grid to place it. The object will snap to the grid position.
3. Object Manipulation: Use on-screen controls or keyboard shortcuts for:
   • Placement: Place an object on the grid.
   • Rotate: Rotate the direction of the object before placement.
   • Delete: Delete an object from the grid if it exists.
4. Grid Visualizer: Visualize feedback for object manipulation and toggle grid cell rendering as needed.

Main Systems

Grid System

The Grid System is the backbone of the project, responsible for:

• Grid Creation: Generates a 3D grid based on specified dimensions and spacing.
• Grid Visualization: Renders the grid lines within the 3D space to aid in object placement.
• Grid Configuration: Allows customization of grid parameters.

Object Manipulation System

The Object Manipulation System handles the following:

• Object Placement: Users can place objects on the grid.
• Object Rotation: Users can rotate objects before placing them on the grid.
• Object Deletion: Users can delete objects from the grid.
• Placement Validation: Checks if a position is valid (e.g., not occupied) before placing an object.

Placement Validation System

The Placement Validation System ensures objects do not overlap by:

• Grid Data Checks: Performing real-time checks during object placement and movement by check data of grid.
• Feedback: Providing visual feedback if an object cannot be placed.
