do you know how to creat a “high score” sprite ?
What do you mean? If you want to do a dynamic sprite text to show the score then you need a text object 
oh, sorry for my bad english i mean how to creat “highscore” and “score” after the character died 
Don’t worry, and excuse me the delay, exams time here 
You need two variables: “score” and “highscore”. During the game the player increases the “score” variables (or decrease it, or whatever depending of the game), finally when the player dies you have to check if “score” (current score of the dead player) is better than the “highscore” variable, if so replace the value of “highscore” with the new better value.
The “score” variable can be a scene variable if the dead sequence is not another scene, otherwise when you switch to the dead scene you lose the score (in this case “score” should be global).
For “highscore”, if the variable is saved through the storage actions (in an external file), you can load the value from the file at the beginning of the game and store it in a global variable, and when replacing with a new highscore replace both the “highscore” global variable and the value in the external file.
Let me know if something is not clear, or if you need other info
