关于回调后，场景无法暂停的问题，请帮助我

[dasdssdasdas]

Here is my code.When the execution scenario "pauses", regardless of whether parameters are added, an error will be returned: "Cannot sleep non running Scene Example".I also used 'sleep()', which is the same. I don't know why!

But I use 'this. scene. start ('Example') ', which can perfectly jump through scenes.

Later, I tried to call a timer (triggering the scene 'pause'), which could be executed correctly.

I find it difficult to understand why, it feels like it's a problem with the direction of 'this'!

layer.setTileIndexCallback(6, (player, tile)=>{
this.scene.pause()
// this.scene.pause('Example')
// this.scene.start('Example')

})

Please help me! Thank you very much. Thank you!
