How can I stop cpu from spawning units in skirmish defense or BvB? And how can I increase my own start money? I basically just want to have a sandbox mode. I tried messing with different lua files but nothing works. Right now, I'm resorting to putting tunnels across the top of the map to stop ships from flying in.

1)Find the corresponding lua file like "SkirmishDefense.lua", open it.
2)If you don't want any enemy to be spawned, find "if self.CPUTeam ~= Activity.NOTEAM and self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) <= 0 and MovableMan:GetMOIDCount() <= 210 then", add some code to make it not possible, for example, "self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) > 100 and self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) <= 0" will never come true.
3)Find

x for the start money, y for the team, z for the difficulty. Just change x as you like.

#2 causes an error and console pops up.

I have tried putting the code in after the aforementioned line or just replacing it but neither works.

replace "self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) <= 0" with "self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) > 100 and self.ESpawnTimer:LeftTillSimMS(self.TimeLeft) <= 0".

Thanks that worked perfectly
