A simple way to use skiptoset in levels.txt. It only skips the title screen going straight to the select screen. It depends on what game mode you are going for/to. Never "Start Game". Never "Choose Mode"/ "New Game".
It would be better if you're new to scripts. Take a look at the manual and the script references. Understand the entity identifier, along with the values.
Update: Found a way to separate my tutorials follow the below links for each tutorial and added a tutorial for the powerful "if statement" once you lean this you can start making custom scripts.
Before you start I want to say sorry if my guide is not very easy to follow this is my first written guide and yes this a very simple introduction if this is useful to anyone then I will be slowing moving onto more complicated scripts in the future.
