Switch Levels Upon A Certain Score Being Reached. Restart At Beginning.

I have a few of questions here and would appreciate any help.
Basically i need each level to end after a certain score is reached. Then upon character death i need the game to end and the restart button to return the player back to the beginning scene. The character will not move in this game.

I have achieved this with multiple worlds and event observers but cannot get the game restart button to revert back to the beginning level (World).
My first question is how would i achieve this?

I then thought that perhaps i should be looking at 1 world with multiple scenes.
My second question is would this be better for game performance?

And Finally how would i do this if the character does not move?

Thanks in advance, there may well be an obvious answer here which i've completely overlooked.

 

Could you not use Event Observers and different UIs for each World? Then use a default button to take you back to that World?

Or look into Check Points?

It really depends on your game.
Do you have a video?

 

Hi Aaro, thanks for your help. Ive currently got a setup with different worlds. I have an event observer on the first world which switches the player to the second world once they have 2 points.

However upon death of the character on the second world, the game then starts back at the second world without even passing to the Game Over UI.

I think it may be an issue with the event observer as the game wont technically end.

Update: The game will now end, that was a simple navigation error. However i think because the first event observer is set to 2 points, the game will only restart at the second world.

 

The "Restart" button will only ever take you to the last known World, i.e. the World the UI is attached too.
If you want a Restart button to "Restart" on a different world, just use a "Default" button and drag the node yourself or use a Back Jump button and select the World from the Drop Down Menu.

 

Ah i see. Thanks i've changed that. However the game still reverts back to the second scene which makes me believe its got to be the event observer somehow.

 

It Appears ticking this box in each world sorts the world selection problem!

 

You could also use an unlock button that can specify exactly where to go in whatever world and whichever scene.
