setPos crashes ofp - help !

[TYsiEK 0]

Hello guys.

I got pretty big problem

I made the script that creates Tomahawk missile some 50 meters above the marker. It looks like that:

_xPos = getMarkerPos "uav" select 0

_yPos = getMarkerPos "uav" select 1

_zPos = getMarkerPos "uav" select 2

_missile = "CoC_TomahawkBlock2BLU" createvehicle getmarkerpos "uav"

_missile setPos [_xPos,_yPos,_zPos + 50]

"uav" is some kind of gps marker I made the script where marker follows vehicle/soldier .

So the problem is... when running script, Tomahawk missile is setting at 50 meters just above the marker and OFP crashes

I know guys it's very funny hehehe .

This is an error report:

Does it crash _after_ the setPos or before? Try <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_missile = "CoC_TomahawkBlock2BLU" createvehicle [_xPos,_yPos,_zPos + 50]Maybe CoC replaces the missile via init EH with something...

I'm not sure if this'll cause a crash but, AFAIK, markers only have 2d positions so _zPos can't be anything.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_missile = "CoC_TomahawkBlock2BLU" createVehicle [_xPos, _yPos, 50]

Raedor, it crashes after setpos. Your example code is working but missile is not creating 50 meters above the ground, but just on the ground at elevation zero

Nindall, I know, markers position are only in 2d but it works if you type _y height too as I typed.

So how to create the missile not on the ground but above it without crashing ofp ?

EDIT

I forgot to tell you that:

_missile = "CoC_TomahawkBlock2BLU" camCreate [_xPos,_yPos,_zPos + 50]

It crashes ofp too after camcreating.

Nindall's point still stands. The reason your missile is being created on ground level is the bad _zPos your using.

You should only need this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_xPos = getMarkerPos "uav" select 0

_yPos = getMarkerPos "uav" select 1

_missile = "CoC_TomahawkBlock2BLU" createvehicle [_xPos,_yPos,50]

BTW Does it crash if you try this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_missile = "CoC_TomahawkBlock2BLU" createvehicle [0,0,50]

If it does, it's either a problem with the addon, or something your missing thats required for the addonis init event, as Raedor said. Have you changed anything in it's config or pbo?

I didn't change anything .

According to my tests getMarkerPos and markerPos return the height value, it will just be zero. So it is not a bad value.

This is what I wrote to some other forum about position arrays as arguments and return values:

<span style='font-family:Courier'>FUNCTIONS WHICH TAKE POSITION AS ARGUMENT TESTED IF THEY

ACCEPT BOTH 2D AND 3D POSITION TYPES.

setPos              X                   X

setWPPos            X                   X

To be absolutely sure, I tested all commands which return a position array:

buildingPos      

getMarkerPos      

getPos          

getWPPos      

markerPos      

onMapSingleClick

position

waypointPosition

All of the above commands return a 3D position array.</span>

Tests for the return values were a simple hint format ["%1", command] which always gave a 3D position array to the screen so the height value was in the returned array in every case. I can't see any reason why the height value returned by getMarkerPos could not be used. It is zero but it still is a perfectly valid value which can be added to and multiplied etc. the normal stuff you can do with numbers. I tested the code from the first post by creating a couple of shells 50 meters above a marker and it worked fine, nice explosion. The code was exactly the same but the classname was changed to "Shell125".

I just ran your original code with no problems -

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_xPos = getMarkerPos "uav" select 0

_yPos = getMarkerPos "uav" select 1

_zPos = getMarkerPos "uav" select 2

_missile = "CoC_TomahawkBlock2BLU" createvehicle getmarkerpos "uav"

_missile setPos [_xPos,_yPos,_zPos + 50]

Although the missile falls rather than flys! (IIRC you need to create a pilot.)

[Guest [B.B.S.] T_D]

afaik missiles have to be created above sea level. So maybe you should use fSetPosASL function to create the missile.

True, but in this case the CoC Tomahawk is a vehicle piloted by the AI.

Quote[/b] ]I didn't change anything

It does sound like your copy of the Tomahawk is corrupt or some other addon\code elsewhere, is crashing OFP.

I'm just testing scripts

The script looks like that:

_missile = _this select 0

_pilot = _this select 1

_uav = _this select 2

_pos1 = _this select 3

_xPos = getMarkerPos "uav" select 0

_yPos = getMarkerPos "uav" select 1

_zPos = getMarkerPos "uav" select 2

#position

goto "createmissile"

#createmissile

I wanna remake Dragon Warrior UAV and add two HellFire rockets because there is no single Predator UAV add-on to download.

Here you got the link how iraqi guys who is setting up roadside bomb dying because of UAV's HellFire boom

In the second video I'm not sure is it Cobra or UAV. But I think that should be some helicopter

UAV HellFire

Car hit by rocket

Have a nice watching

For this time I'm using UAV and CoC Tomahawk radio strike. It's a lot of fun .

This might cause OFP to crash:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_pilot = "soldierWB" camCreate [(getPos _uav select 0),(getPos _uav select 1),0]

If you don't create a pilot\driver with CreateUnit and a valid group. It can cause OFP to crash when in certain vehicles, at certain times.

As a test you could place an infantry guy in the editor and move him into the pilots seat instead, to see if that solves the problem. If it does it's just a case of getting a valid group and using CreateUnit.
