How do you add multiple BSP's into one level? Is it trigger volumes?

Simple. Go to Guerilla, scroll down to 'Structure BSPs' and click 'add'. Then add which structure BSPs you want.

Then when you want the player to switch, add this command:

switch_bsp [BSP NUMBER]

To your script. Note that BSP number is the number given to your BSP in the list in Guerilla (first BSP is 0, second is 1, etc)

What's the script? I'm not a scripting expert

If you wanted, say, to wait until you step in a certain area and then switch BSPs, then it would be

(script startup bsp_switch
(sleep_until (volume_test_objects <trigger volume name> (players))15)
(switch_bsp <BSP #>)
)

Bear in mind, however, that the player usually will not spawn normally when you switch. You can make the player teleport to the place you want to, though.

Thanks man I'll try it tomorrow to see if it works

You can also make it so when the bsp switches, you can make a checkpoint.
