How to make a change spawn like a checkpoint but can be done again?

Does anyone have a script were, if i step on it and die i will spawn there, and if i step on another one i respawn there ANDD, if i restep on the previous one i will spawn there!?

Well, this is not really a scripting problem but you can use the teams function to change your team once you stepped on the spawn location. Basically, set the property of the Spawnpoint to AllowTeamChangeOnTouch and create a team so when you stepped on the Spawnpoint it will make you spawn there.
