Dynamically limit the next immigration wave.
Limit the number of migrants that can arrive in the next wave by overriding the population cap value from data/init/d_init.txt. Use with the repeat command to set a rolling immigration limit. Original credit was for Loci.
If you edit the population caps using gui/settings-manager after running this script, your population caps will be reset and you may get more migrants than you expected.
max-wave <wave_size> [max_pop]
max-wave 5 repeat -time 1 -timeUnits months -command [ max-wave 10 200 ]
The first example ensures the next migration wave has 5 or fewer immigrants. The second example ensures all future seasons have a maximum of 10 immigrants per wave, up to a total population of 200.
