Decompose your sentence into condition and action.
" game change the scene when the character comes into contact with an object"
What you need ? A scene, a character, an object.
What is the condition?
What is the action?
Now you have the anwser, and you can open the eventsheet editor add an event add a condition and search in the condition list, and do the same thing for the action.
But if you are new here, i recommend you to start with a tutorial. Click on Wiki on top of this forum.
