Hey, first things first let's fix the imports. The import of the file you are trying to import should look like this:
import("Prototype/VPTickerWin-Annihilate_Functions.scar")
Now for the gamemode. To check if an entity or squad died I would advise you to use function called
Rule_AddGlobalEvent(rule, eventType). As
rule you should put in a function that will be executed everytime
eventType is triggered. And as eventType you can put in
GE_SquadKilled or
GE_EntityKilled that is up to you what you chose.
For the rule function, you can use
Setup_GetWinConditionOption() function that will return the number of VPs the player selected to play with. With this, you can do whatever you want your function to do. I would also recommend doing a Lua table of all entities you want to affect the VPs. In the table, you could also set for different entities different VP bleed, etc.
