spawn hero after lose

Let's say, before reaching the pokecenter, I lost in the grass pokemon(faint) and how can I teleport to a town to a certain person? as well as there is a list of saving progress. After losing, you teleport to the pokentsentr. And it depends on the progress of the game. How to calculate it? The initial script from the mother does not work. due to changes in the starting point of the game
