Slope? How to set it? ?:-o

[MorMel]

I'm creating a guided missile script which sets the direction of a camcreated projectile, according to the targets position. Unfourtunately, when the missile crosses with the target, it will proceed its trajectory as its height is too high... and i wan it high! How to make the missile crash with the target?

P.S.: i tried "_missile setpos [_x,_y,(_h-_fac)]" loop type. it didn't work...

[MorMel]

Come on!!!! :-\

Nobody knows how to define a rocket's slope...  

I just wan'it to blow over ma target... Set its z position to z-0.1 on each loop but it isn't realistic..

C'mon u guys... A kno u can solbe eet  

[MorMel]

OK, OK!!
You don't know how...    :-\

But do you know how to get a vehicle's height from the sea level (not from the ground, off course)...  

Be sure not to use post OFPv1.00 commands,

[HuNtA]

Use the getBank and getPitch commands for the direction and just have a gamelogic where you want to check where the height is and use:
missile distance gamelogic <= height
or something like this

[MorMel]

Hummm.... I think i didn't understood... Are GetPitch and GetBank v1.00 compatible? What's their syntax?

But don't give much importance to that... i'll check it out by my self.

   Now, about your explanation, i think you're failing with the 'distance' command. You must use some trignometry before getting the missile's height above the sea level:

1st, place the gamelogic over the sea.

(missile distance gamelogic)^2 = HorizDistance^2 + MissileHeight^2

Then - [_x,_y] : missile's position; [_i,_j] : gamelogic's position

_Height = (missile distance gamelogic)^2 - SQRT( (_x-_i)^2 + (_y-_j)^2)

And I think that's it! I got the missile's height above the sea level!

Thanks man!!! The "gamelogic" idea is just great!!! ;D

This way i can verify both the missile's and the tank's height and-then-set-the-missile's-height-to-the-tank's-height-and-then CABOOOOMMMM!!!!

wait... you have version 1 of ofp? you need to update dude

[MorMel]

wait... you have version 1 of ofp? you need to update dude

YEAH, YEAH! I know... but what shall i do? I can't find it!!!

Now, about this thread:

This thread was open with the objective of providing the necessary commands and maths for creating an ATGW script. Unfourtunately i realized that rockets are too instable, therefore it became useless as a ATGW script...
But Wait! What about a true projectile, night effects included, artillery script???!!!

That's it. Thanks to the "gamelogic" idea i invented one, very realistic (i think)

Where _Ref is the gamlogic for sea level reference; _Orig, the origin of the art projectile; and _Target, you know, the target object. All of these are objects.

About the script:

This script seemd effective, reliable, yet it experiments some failures:

- Precision
- Abrupt end of script when i fire multiple rounds

Could anyone find the problem?



Just one more thing:

As i'm using OFPv1.00, i have NO IDEA how OnMapSingleClick works.
Could someone explain me? Or even create a script which initializes the main one?

I'll be thankfull!!!  ;D


P.S. - One more time, I wanna thank HuNtA for the "gamelogic" idea.  

AH! I authorize anybody in this forum to use this script (As long as you give me credit, off course   )

[MorMel]

Code: [Select]

I have just add one more effect to the script:

_FX2 = "SmokeShell" CamCreate [0,0,100+(random 100)]

Then i just gotta add it to the next few lines where the FX position is updated:

_FX2 setpos [(GetPos _orig select 0)+_n*(cos _dir),(GetPos _orig select 1)+_n*(sin _dir),_h+0.5]

This will give the projectile a cool rocket tail effect...

One more thing:

I realized that the "Abrupt end of script when i fire multiple rounds" happens if i fire more than 8 rockets with 0.2 time gap between eachother. Therefore i made a paralell script which activates the main one and avoids the script stoping:

Code: [Select]

[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.2
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.9
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.2
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.9
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.2
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.9
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
~.2
[Ref,MyTruck,MyTarget] exec "ARTT.sqs"
exit

It's like a MLRS!! Seems nice on OFPv1.00...

About Precision: I just changed the "reentry" method and changed
<? GetPos _shell select 2  < 15 : _FX setpos [0,0,0]; _FX1 setpos [0,0,0]; exit>
by
<? GetPos _shell select 2  < 15 : _shell setpos [_i,_j,_TH+3]; _FX setpos [0,0,0]; _FX1 setpos [0,0,0]; exit>

where _i and _j are the coordinates of the target. Unfourtunately it seems too precise... and if it is a moving target, it would be a kind of strange to see a missile falling over a position and blowing at another... ;D This way we should allways use static targets... Or just have a direction update script, but it will look like "guided artillery"...

I'm open to improvement proposals for this script!

[Ranger]

YEAH, YEAH! I know... but what shall i do? I can't find it!!!

Umm, I don't mean to be rude, but if you can't find the update patches, you are pretty sad.    ;D

Just go to the official OFP site!!!

[MorMel]

I wanna posts about the script and how to solve its problems, please.  

I know how to find the things I need with the resources I have...
