Missile to specific position

[Barba-negra 117]

good morning, how are you guys? I'm asking for help because I'm not sure I know how to do it, I want to create a simple scripts for a missile that is fired from a ship called ship1 and that it moves up, and then moves to the direction of a goal already created called boat2, then I did something like this:

 

cohete = createVehicle["Missile_AGM_02_F", barco1,[],50,"FLY"];

 

cohete setVelocity [0, 0, 20];
Sleep 0.5;
cohete setVelocity [0, 0, 20];
Sleep 0.5;
cohete setVelocity [0, 0, 20];
Sleep 0.5;
cohete setVelocity [0, 0, 20];

 

So far I have it but I do not know how to do so that once you reach the desired height the rocket moves to the ship2, please help guys

This should have all you need.

hello friend, if I have seen that scripts and I have seen others, but that is called by laser destination, and others that I have seen is by clicking on the position of the map, but I need to appear as well as calling a scripts, currently the missile appears , and moves up, but I do not know how to adapt the objective later, how could it be added?

[Barba-negra 117]

I'm reviewing this command but I do not know how to adapt it and see if it works

i actually adapted that script so it was spawned with an offest to the source vehicle (i.e. a plane) and the target is just passed in params so no laser designator required. For my use it was to allow missiles to be used by AI side but it might have some ideas for you

deleteVehicle _fireLight;
deleteVehicle _secondaryTarget;

sleep _missileDelay;
hint "Missile available!";
LF_missileAvailable = true;

};

 

then it is spawned like so:

 

Quote

[_vehUAV,10,"ammo_Missile_Cruise_01",200,_quarry,getPos _quarry] spawn LF_fnc_cruiseMissile;

 

EDIT: this works ok when fired from the air but if its being launched from ground then you might still need to insert your lines to make the missle fly upwards first

[Barba-negra 117]

I do not understand very well LordFrih, could you show me how to do it?

[lordfrith 401]

well put the function above in your init.sqf so its loaded then try calling it with something like:

 

Quote

[ship1,10,"ammo_Missile_Cruise_01",200,boat2,getPos boat2] spawn LF_fnc_cruiseMissile;

 

but as i added above you might need to make the missle fly upwards first before moving towards target as i was writing that to be launched from plane so missile already has altitude

[Barba-negra 117]

 

Thank you! @lordfrith I'm going to try it

[lordfrith 401]

well i needed to do this too at some point so i've been messing about, see revised function below, i've highlighted in red the lines which set where the missile spawns and how long it flies up for

 

this is in my init.sqf to test, i forgot to add the line 'LF_missileAvailable = true;' in init or the function will kick off with an unknown variable error

seems to work pretty sweet now, heres my test scenario, enjoy!

[Barba-negra 117]

Exactly I was already writing to him that he was giving me a variable error

 

 

 

[Barba-negra 117]

friend and what part of the scripst can I add to start flying up?

[Barba-negra 117]

OHHH Magnifico, I just saw it is beautiful :o

[Barba-negra 117]

Thank you very much @lordfrith I spent a lot of time trying to do this

check my revised script in my last post i added it already ;) , its the line

[Barba-negra 117]

thanks :D

[Barba-negra 117]

@lordfrith a question once the missile goes in the air, if the target ship moves, the missile will follow it, or will the missile fall in the previous position of the target?

 

[Barba-negra 117]

and another question bro, how do I change the speed of movement?

yep, with unnerving accuracy, serious, you can't hide from this thing! try running it with yourself as a target then try fleeing! 

 

I'd use it for scenes or AI support calls, for players its more realistic to use the original laser pointer target one

[Barba-negra 117]

ok thanks @lordfrith Now I'm going to do something more complex, like I'm working on a boat, I'm trying to create a torpedo system with the same scripts, so far I've put the torpedo and it works very well, only now the torpedo is an object and not ammunition, then try to put a ammunition and touch the water it explodes, it is something more complex this second part of the work

[Barba-negra 117]

I could solve it for now, I already managed to create the torpedoes, I'll be doing tests
