Randomising AI skill & fuel

[Salmo]

Tired of AI flights that behave the same every time a mission is played? So am I. Let the mayhem begin :)

Well done Salmo and thx for sharing.

Awesome stuff. Do you copy and past everything into a .cs file or just part of it?

The script was designed for server missions or scripts that use the gpPostMissionload method to load a sub-mission into the battle after the battle starts. If you're doing this, then just copy-paste the SalMissionLoad routine into your script & replace all occurrances of GamePlay.gpPostMissionload(MissionName) with SalMissionLoad(MissionName).

Ok so with SalMissionLoad(MissionName) the randomisation will happen as the mission loads and before "Start Battle" is hit, and GamePlay.gpPostMissionload(MissionName) will load once "Start Battle" has been hit? My objective is to create a co-op style mission with several groups of AI aircraft that I want to make random ideally before anyone spawns in.

Many thanks

Not quite. SalMissionLoad is in your main mission's script, & calls (loads) a sub-mission into the main battle. It randomises Ai skill (& other Ai atributes) as it loads the sub-mission. here's what to do:

1. Make 2 missions, a main mission & at least 1 sub-mission.
2. The main mission should contain all those things you want in the battle (ground objects, statics etc) except the Ai aircraft.
3. The submission should contain only the Ai aircraft.
4. Now get the main mission script file to load the sub-mission after you start the main mission (battle start). Here's the code for the main mission script file. Note the OnBattleStarted routine code.

private void SalMissionLoad(string MissionName)
{
//================================================== ========================================
// Purpose: Randomises certain charactistics in the specified mission file
//
// Input: Mission file name
//
// Output: A temporary mission (text) file, which is deleted after mission is loaded
// into the batle
//
// Use: Replace all occurrances of GamePlay.gpPostMissionload(MissionName) in
// in your C# scripts with SalMissionLoad(MissionName)
//
// How it works: Reads specified missionfile one line at a time & writes each line to a
// new (temporary) mission file. When a 'skill' line or 'fuel' line is found,
// the script will construct a new line with randomised parameters for these
// charateristics. Once reading the mission file is completed, the temporary
// mission file is loaded into the battle & then deleted.
//
// Works best if, in FMB, you select a one plane in the Ai flight & give it
// a custom skill level (change at least 1 skill parameters). This will force
// FMB to write a seperate skill line in the mission file for every plane in
// the flight. If you don't do this, the the entire flight will have just one
// skill line in the mission file & randomising skill will result in all planes
// in the flight having the same skill level. ie. All will be rookies or
// average or veteran or aces, which is probably not a good idea.

Hello Salmo

can you give us an overview with a folder with a mission and sub-mission? (downloading)

To better understand how it works.

Thank you for the work done in the script for COD.

Forgive me for my English.Nacy (FRANCE)

Hi Salmo,

I cant get this script working.Some time ago on the IL2-CoD forum you gave me (as Lookaloft) some nice advice about your script Ship oil fire effect so I venture to ask you helping me out for a second time.

I have made two single missions. Main mission (with some objects, statics and me flying a spitfire) and a submission (a flight of ai-ju 88 bombers). Main mission got the name Sal, the submission: SalSub and your script: Sal.cs. I saved these files in one directory named Sal in Mydoc\1CSoftClub\il-2sturmovik cliffs of dover-MOD/missions/Single/ ....
Then I started up the main mission but no luck, couldnt find the Jerrys.
The script was in the main mission. Compile: OK.

With regards,
Barraclough.
