This is what it should look like.

Now save and open PoryMap.
Go to the same map that you pasted the script into.
Now go to the Events tab.
Add 3 new Objects and place them where you want. (Make sure they are in order from 7 to 9 or else you'll have to modify the script)
On the first one you'll want to give it the script.
while you are here you can give it the sprite you want.

Script_OgSS_1

Now for the Event Flag

FLAG_UNUSED_0x2B9

Now for the second objects script.
you can also set the sprite.

Script_OgSS_2

And the seconds Event Flag.

FLAG_UNUSED_0x2BA

Now for the last objects script and sprite.

Script_OgSS_3

And the thirds Event Flag

FLAG_UNUSED_0x2BB

Now you should be good to go!
If you dont understand something or if something doesnt work properly let me know so i can try and fix it.
Also feel free to modify my script to your liking.
