What is a flag and how do I add one to my mission?

[Studsmcgee]

I've been reading about mission building and I see a lot of references to "Flags".

 

From what I understand they are a true false condition that can trigger other events.

 

What I don't understand is how to add one in the mission editor. Nothing I can find says "add flag" or anything like that.

 

I'm sure it is a simple procedure but I can't seem to figure it out.

 

Thanks

All flags already exist within a mission and they are set to false by default. There is no need to add a flag or set a value for it to be used.

You can use Flags in the action- and condition column of the trigger list.

In the action column you can set a Flag to true or false or set it to a specific or random value.

In the condition column you can ask if it is true or false or if it has a specific value.

 

A Flag is nothing you can see in the mission. It is used to get a trigger logic, to "save" a state of something to use it in a other trigger.

Or you can interlock two triggers so only one trigger can be active at the same time.

The use cases of Flags are endless.

Also, flags can be increased or decreased in value; they are not just True/False.

 

You can start a flag with Flag Increase, say for Flag 10, increase by value 1, and Flag 10 will go True with Value = 1.

 

You can decrease Flags in the same way and they will go negative in value. I do not know if decreasing a flag through zero will cause a False condition for that Flag at zero - when I tested Increase & Decrease I looked at the numerical value and not at the Boolean value.

 

I got some help with this, happy to share it -

Displaying Flag Values with text messages

 

Use a Do Script Action -

local msg = {}

msg[#msg + 1]='Blue All Points Flag 10000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('10000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='Blue Vehicles In Zone Points Flag 20000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('20000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='. \n'

msg[#msg + 1]='Blue Aircraft Points Flag 50000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('50000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='Blue Heli Points Flag 60000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('60000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='Blue Vehicle Points Flag 70000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('70000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='Blue Ship Points Flag 80000 value = '

msg[#msg + 1]=trigger.misc.getUserFlag('80000')

msg[#msg + 1]='. \n'

msg[#msg + 1]='\n'

msg[#msg + 1]='Press Pause to freeze the action. \n'

trigger.action.outText(table.concat(msg), 6)

 

 

Hey Studsmcgee - this post really should be in the Mission Builders Corner, which a sub-forum to this forum. ^^^ Hope this helps.
