In Unity, the execution order of scripts can be controlled through the script execution order properties. These properties determine the order in which each script executes in the Update, LateUpdate, and FixedUpdate functions in Unity.<\/p>\n

The execution order of Unity scripts is as follows:<\/p>\n

    \n
  1. The Awake function of all scripts is executed based on their order of execution attribute.<\/li>\n
  2. The Start function of all scripts is executed based on their execution order attribute.<\/li>\n

    It is important to note that Unity executes scripts in parallel, so there may be issues with the order of execution between different scripts. To avoid this problem, you can manually set the execution order property of scripts to ensure their execution order.<\/p>\n","protected":false},"excerpt":{"rendered":"
