I need help about respawning

Help
1

I want to respawn my character at the selected spawn point. Basic Respawn Settings is not what I want.

you can use the Respawn() method of player objects to respawn players at specific locations.

--The line below is not actual code I am just using it to demonstrate
--that you need to have access to some player object
local player = [some player]
local respawnPosition = Vector3.New(100, 100, 100)
--Respawn the player at the "respawnPosition"
player:Respawn({position=respawnPosition})

Can I get SpawnPoint's location from the map?

You could attach a core object reference custom property to the script. This core object reference custom property would refer to the spawn point object that you want players to spawn at.

--Core Object reference to the spawn point object
local spawnPoint = script:GetCustomProperty("SpawnPoint"):WaitForObject()
--The line below is not actual code I am just using it to demonstrate
--that you need to have access to some player object
local player = [some player]
local respawnPosition = spawnPoint:GetWorldPosition()
--Respawn the player at the "respawnPosition"
player:Respawn({position=respawnPosition})

I would recommend looking through the "Cor eObject" documentation:
