Trying to understand sqf...

[Blanco]

Hello, I've found a script to place the player on the roof of a moving truck. The player is not able to move, but that's not my problem.
I want the script to exit via an addaction, but I don't know how to do this to do in sqf format. Actually... in sqs either 

Here is the script:

_Unit=_This Select 0;
_Vehicle=_This Select 1;

_Unit SetPos (_Vehicle ModelToWorld [0,-3,1.26]);

//STARTTRUCK=True;

WaitUntil
   {
   _Unit SetVelocity (Velocity _Vehicle);
   _Unit SetPos (_Vehicle ModelToWorld [0,-3,1.27]);
   _VUp=VectorUp _Vehicle;
   _VDir=VectorDir _Vehicle;
   _Unit SetvectorUp _VUp;
   _Unit SetvectorDir _VDir;
   };

First question...

Is the line //STARTTRUCK=True; a comment? When I delete this line the script still works.

Second question...

I think the position & vector of player and truck needs to be updated when the truck starts moving, but I don't see a loop here...
Waituntil doesn't create a loop AFAIK. Where is the condition?

Third question...

How can I exit the script via an addaction? I want to create an action "jump of the roof" that exits the script. I would add one of the rollanimations when the player gets of the roof to make it look better.

Left roll =  "amovppnemstpsnonwnondnon_amovppnemevasnonwnondl"
Right roll = "amovppnemstpsnonwnondnon_amovppnemevasnonwnondr"

 
PS: I've read Cheetah's basic sqf tutorial but I still don't get it

da exiting part shud b easy.... u just add condition

Code: [Select]

?nameOfVariable : exit
inside ur loop

and in da addaction script u just put

Code: [Select]

nameOfVariable = true
also dont forget 2 init da nameOfVariable 2 false

bout ur function... i 2 cant understand da waitUntill thingy... as it doesnt follow da syntax in COMREF 

_i = 0; waitUntil {_i = _i + 1; _i >= 100}

it doesnt seem 2 have condition attached ?

Aha LCD is back
I have to learn my LCDish again 

OK, I could fix it.

ontruck.sqf
X = [Name of unit, name of vehicle] ExecVM "onroof.sqf"

_Unit=_This Select 0;
_Vehicle=_This Select 1;

_Unit SetPos (_Vehicle ModelToWorld [0,-3,1.26]);

onroof = true;WaitUntil
   {
   _Unit SetVelocity (Velocity _Vehicle);
   _Unit SetPos (_Vehicle ModelToWorld [0,-3,1.27]);
   _VUp=VectorUp _Vehicle;
   _VDir=VectorDir _Vehicle;
   _Unit SetvectorUp _VUp;
   _Unit SetvectorDir _VDir;
!(onroof)};
exitWith;

Onroof is the variable to exit the script and is set false in the init and addaction script.

I tried to create the addaction in the onroof.sqf but I got an missing error...

The rolling part doesn't look like I expected and the player got hurt when he jumps of the roof even on a stationairy truck

aha blanco que paso ?   

so now it kills da script ?

i dont remember much of da functions but i think dey r more suited 4 math stuff nd da like nd not 2 do stuff like what u do ? but im not sure about dat... so mebe dats y da addaction didnt work in da screen itself

as 4 da getting hurt... best u cud do is set his dammage 2 whatever it was b4 dat i guess ? cuz it seems Arma soldiers really dont like heights  also i suggest maybe finding a nice anim 2 play when he jumps down ? or something like that ?

I have no idea

as 4 da getting hurt... best u cud do is set his dammage 2 whatever it was b4 dat i guess ? cuz it seems Arma soldiers really dont like heights

I store his damage in a variable before he jumps of the roof and add again when he's back on the ground. Seems to work.

This is the addacation script right now:

onroof = false

_dam = getdammage player
player removeaction 0

; from prone to crouch"
player playmove "amovppnemstpsraswrfldnon_amovpknlmstpsraswrfldnon"

;waituntil the player is on the ground
@(getpos player select 2 < 0.5)

~0.2
player setdammage _dam
exit

also i suggest maybe finding a nice anim 2 play when he jumps down ? or something like that ?

Yeah, i was looking for a good anim, maybe the "climb down ladder" anim?

Thx, I already have the animviewer.

I have made an excel file with most animnames + a short description. Oranised in 3 worksheets : stand, crouch and prone, but no death or cargo anims.
You can use the list while your scripting instead of switching between the animviewer and the mission your working on..

I would use a while with sleep inside instead of waitUntil

Code: [Select]

_Unit=_This Select 0;
_Vehicle=_This Select 1;

onroof = true;
_actionidx = player addAction ["Jump", "jump.sqs"];
_Unit SetPos (_Vehicle ModelToWorld [0,-3,1.26]);
while {onroof} do
{
   _Unit SetVelocity (Velocity _Vehicle);
   _Unit SetPos (_Vehicle ModelToWorld [0,-3,1.27]);
   _VUp=VectorUp _Vehicle;
   _VDir=VectorDir _Vehicle;
   _Unit SetvectorUp _VUp;
   _Unit SetvectorDir _VDir;
  Sleep 0.002;
};
player removeAction _actionidx;


Code: [Select]

;jump.sqs
onroof = false

;Whatevet you want to add here


exit
