Custom radio options based on visibility of target

[nomdeplume]

It would be really nice to be able to have the mission react to what the player sees. Since it's rather difficult to determine what a player has/hasn't seen, one idea for implementing something similar would be as follows:

 

1. New trigger action 'add conditional radio item' or similar. This would take parameters:
   
   • Group/Unit/Static object of interest
     
   • Max distance from SOI/SPI to activate radio option
     
   • Radio option text
     
   • Flag number
     

[*]When the above trigger action is run, adds the parameters to an internal list of conditional radio items. They could be removed with the existing 'remove radio item' action.

[*]When the 'F10 other' radio menu is opened, process any conditional items in a similar manner to the "Contact" report to the JTAC:

• If the identified Unit or Static object is within the specified distance of {SPI,SOI,any sensor} (not sure what the best implementation would be, probably SOI?) then the item text is added to the menu.
  
• If the identified Unit or Static object isn't within the specified distance of the SOI, then skip the item (won't appear in the menu).
  

[*]Player can then activate the radio item if they were looking in the correct location when they opened the menu.

Another implementation would be to have a flag set & unset when the watched object is inside/outside the specified range of the SOI. This would need to happen continuously so might be expensive in terms of performance even with only a few objects being watched, but would provide greater flexibility.
