Help with LUA x2

[JmrjMrjmR]

Hi there fellow aviators!

I am new to mission editing and scripting in general and want to add extra nice features to one of my missions. Let me explain :

Exhibit A (Warning shot)

I want an enemy airplane (let's call him Red 1) to wait 5 seconds after a friendly airplane (let's call him Blue 1) fires its cannon past his nose before turning back to base. Here is what I have so far that doesn't work. I have set a 1000' moving zone around Red 1 (let's call it Red Zone 1) and called two triggers as follows:

Trigger #1
Type: ONCE
Event: ON SHOT
Conditions: WHEN PART OF GROUP BLUE 1 IS IN ZONE RED ZONE 1
Actions: SET FLAG 10 = 1

Trigger #2
Type: ONCE
Event: NO EVENT
Conditions: TIME SINCE FLAG 10 = 5
Actions: AI TASK SET = SWITCH WAYPOINT 2 (the RTB point)

The problem I encounter is that when I'm shadowing Red 1 (but have not fired yet), as soon as anybody in the mission fires he breaks away.

___________________________________

Exhibit B (Open bomb bay doors)

I have a Tu-95 Bear loaded with anti ship missiles (Let's call him Red 2) and I want to have him open its bomb bay doors (argument 26 going from 0 to 1 gradually) while inside a moving zone around its target (let's call it CV zone 1). Without any triggers and/or scripting the Bear opens his bomb bay doors the second the weapon is launched, giving no chance for the ally aircraft (Blue 2) to react and shoot him down.

 

Help is much appreciated!

i wont use default trigger mission by a while, prefearing script, but if i remember correctly the ON SHOT eventy means every shot in every place so, if you enter the zone with Blu1 and "blu4" somewhere in the map shot, it will trigger the event and red1 break away, because blu1 has triggered the FLAG 10 and blue4 triggered the shot event.

theres a condition called UNITS  HITS SUCCEFUL and you can use that to trigger the flag10 when blue1 hit the target, removing the on shot event, but if you dont hit him nothing happen.

i think without lua can be tricky, can be simple manage that with moose EVENT:OnEventShot(EventData) using event.initiator to make sure that blu1 is the initiator, then UNIT.IsInZone() using the initiator as unit to check if in the moving zone so at this point the trigger only set the flag when blu 1 is in the moving zone and blu1 has shoot something. if blu4 shot but isnt in the moving zone nothing happen.


also about the animation i think without lua scripting theres no way to change the argument. but, i never have myself try that so i cannot say

you need a piece of script for this, e.g.:

local function checkDistance(unit1, unit2, radius)
    local p1 = unit1:getPoint()
    local p2 = unit2:getPoint()
    return (p1.x-p2.x)*(p1.x-p2.x) + (p1.z-p2.z)*(p1.z-p2.z) + (p1.y-p2.y)*(p1.y-p2.y) < radius*radius
end

world.addEventHandler({
    onEvent = function(self, event)
        if event.id == world.event.S_EVENT_SHOOTING_START then
            local red1 = Unit.getByName("red1-1")
            if red1 and checkDistance(event.initiator, red1, 1000) then
                trigger.action.setUserFlag("shot_near_red1", 1)
            end
        end
    end
})

this will react on shooting near "red1-1" unit and set a flag back to the ME you can work with (set ROE, switch waypoint, ..)
attached a demo mission, where red1 is doing orbit, and flees back home once blue shoots nearby

your second thing is not possible, can't animate other units, only read certain animation args

I guess that would mean altering the unit AI so it opens the bomb bay sooner but I don't think that's feasible... Or legal

Awesome thank you so much! Can you show me how to tweak it? I modified Red 1 to be a Tu-22 and Blue 1 to be an F-18. When the Tu-22 started evading and dumping flares it reacted to itself (probably seeing flares as being shot at). I set the bomber to No reaction as its defence and it worked when I shot the gun near him

Also is 1000 a distance in feet? Is it the distance between the firing aircraft and Red-1 or the distance between the bullets and Red-1?

 

Again thank you so much!
