Here is a clean, natural translation in English with the updated explanation and code context:
You can do a manual mapping of the music in a file, like...
| Music | Second |
| 1 | 0:01 blue, 0:02 blue, 0:03 red |
And make a simple script so that when you press "Space", it maps the note—that way you sync with the rhythm and build it as you play
Then, you create a mathematical equation to predict how many pixels it needs to move to hit a target position X, which matches the current second, defining exactly when to hit it:
position.x += equation
It’s similar to how Friday Night Funkin' (FNF) works, just a bit simpler. This lets you sync everything through code in real time. You can store it in a simple .json file and load it later into a global variable, like:
var track_map : Dictionary = Global.TRACK_MAP[Global.level]
I translate this with Gemini, but don't worry. I write it 100%
