The player falls on a platform and is teleported to a certain checkpoint depending on the variable value at the time. Whenever the player touches the chair, it adds a value to the variable (atleast it’s supposed to). For example, if the player touches the chair for the first time, the variable becomes 1 and whenever the player falls onto the platform they are teleported to checkpoint1, and if they touch the chair again then the variable becomes two and whenever the player falls onto the platform they are teleported to checkpoint2.
