How to use multitouch

Can anyone please tell in detail about how to use multitouch.
I wanted to use it in making my platform game to make the character move and jump at the same time. please help me.

A good place would be to check out the platformer example bundled with GDevelop as that works with mobile multi-touch controls.

Generally, the “Touch/Cursor is on Object” condition on your on-screen controls should be enough when the below event is used in addition at the beginning of your scene.
