Laya commercial grade tutorial-5 minutes Laya-A star pathfinding solution
Laya commercial grade tutorial series-A star pathfinding solution
The path finding function is an essential skill for developers. In this issue, we spend 5 minutes mastering how to use the path finding function in LAYA
First, we open the Laya project and the u3d project in the material package separately
The plug-in download address and case source code are at the bottom of the article
We open the prepared LAYA project and U3D project in the
material. The LAYA project only contains characters and scenes.
Our goal is to realize that the characters move around the obstacles and move to the clicked position.
Step 1: Import the pathfinding plugin
Step 2: Configure the pathfinding graph
Step 3: Call the pathfinding API
The pathfinding algorithm uses the pathfinding.js

The second step details:
Creating the scene Gameobject named astarMap, add components Pathfinder, add Grid Graph,
first set the length and width to 0,0, 0,0 center point (this step can not be omitted, the back will do a detailed explanation)
settings Change the length and width to 9X9
connections to four
non-walkable node configuration, set the collision testing Mask to obstacle, and add a collision body for the roadblock object, and set it to the obstacle layer.
Click to generate data
export data
Add the component
AstartExpLayaTool, click exp json (export json data)
to return to the code editor, and assign map data
Compile and run
Note:
Solve the problem that the WeChat platform cannot recognize the class library.
Edit the class library initialization process 
. The requirements for map production;
for performance reasons, the map and the world coordinates adopt a one-to-one correspondence relationship. The purpose is to reduce the coordinate conversion process.
So the
unit The grid size must be the default value 1, and the pathfinding map must be in the first quadrant. The
course materials can be downloaded from the group or official account
