# Setup and usage

## Set up your Database connection (if not WebGL build)

{% hint style="info" %}
If you want to use this in production - your database need to be opened to the world. Otherwise - you will not connect to database. For local connection check your firewall and open database port. Default MySql port is 3306. If you want to use WebGL build - skip this setup and read "Action Use WebGl"
{% endhint %}

Make **Global or Local Variable** that will save your connection string**.** \
Add Trigger "**On start**" and add action "**Mysql Set Config**".

After this use [**Mysql Connect Action**](https://9476764.gitbook.io/rezus13/mysql-for-game-creator/usage/mysql-actions/action-mysql-connect) to make connection to your database! 

#### **This two actions must execute with onStart trigger. Otherwise you will have errors with using other Mysql Actions**

If you have some troubles with this - watch this tutorial video

If everything is good, this action will make a connection string which you will use in other **Mysql Actions**
