Suggestion: If you don't want your variables to show "undefined" before using them you can define them by setting them to some initial value (such as zero) as the scene loads. You do that in one of two ways. 1. define the variable in the text input box located in the upper-left corner of any object in the scene. Simply enter the variable (for example: scene.my._score1 = 0) any time before you save the scene. 2. You can also define them by placing them in the onSpawn event like this example:

onSpawn = (e)=>{
scene.my._score1 = 0
}
