Grid Movement

Getting Started

Requirement

Godot Engine v3.x

Installing as a Project

After downloading, open Godot Engine Project Manager. Click Import, go to the folder you've downloaded, and select "project.godot".

Installing as a Plugin

After downloading, copy the folder "addons/snap_map" to your project file. On your project, go to Project > Project Settings > Plugins (tab) and check "Snap Map"

Usage

Example

The scene contains a player (green) and 2 obstacles (orange and purple). The player can move in any direction, using arrow keys. The obstacle blocks the player's way.

Plugin

There are additional nodes unique to this plugin:

• SnapboundTiles (extended from TileMap) - its cell size can be adjusted such that the grid step for snapping will also be automatically updated.
• PlayingPiece (extended from Area2D) - a playing piece to be moved around a map of tiles.
• ColShapePiece (extended from CollisionShape2D) - its shape size can be adjusted automatically based on changes to grid step.
  • ColShapePieceEx (extended from ColShapePiece) - use this to cover more than one tiles.
• RayCastPiece (extended from Raycast2D) - where it can cast to depends on its direction (Vector2) in proportion to grid step.

If a PlayingPiece has a TileMap as its parent, its grid position can be viewed. To find the grid position, go to the Scene Dock, and on the Scene Tree, mouse over the PlayingPiece.
