random under certain number? [SOLVED]

[Krieg]

I am making an artillery script in which combines onMapSingleClick with createVehicle.

Code: [Select]

_pos = _this select 0
createVehicle "shell125" getPos _pos + randomBut random number could result in 1548415456 which would throw the shell waaay of the island.

My question is, is there a way to make random go under certain number (i.e. under 150)?

Thanks,
Krieg

But random number could result in 1548415456

No it doesn't, unless you use random 1548415456.

And you can't even use it like that with a position since position is in three dimentions: [x,y,z]. It returns an array of values, such as [67543.1,8378.23,0.23476]. When you're dealing with arrays each element in it has to be dealt with individually. Element is an entry in the array separated by comma (or what ever , is called).
The first elements index number is 0, the second is 1, and so on.

The format of the random command is random <number>, so if you set for example random 5 it will return a random number anywhere on or between 0 and 5.

I'm assuming since it's a arty script you would want to have a random position around the given position, within a random diameter. For that you need some trigonometry.

So try something like this:

Code: [Select]

; random diamater between 0 and 150 meters
_randDia = random 150
; random direction
_randDir = random 360
; create shell within the random diameter between 50 and 100 meters into the air
_shell = "Shell125" createVehicle [(getPos _pos select 0)+_randDia*sin(_randDir),(getPos _pos select 1)+_randDia*cos(_randDir),50+(random 50)]
Note that I'm a complete math retard so the trig part maybe completely wrong

Thanks h-!

To my understanding, complete script would look like this:

Code: [Select]

_shot = 0
_randDia = random 150
_randDir = random 360

#bigloop
?(_shot == 50) : goto "exit"
_shell = "Shell125" createVehicle [(getPos _pos select 0)+_randDia*sin(_randDir),(getPos _pos select 1)+_randDia*cos(_randDir),50+(random 50)]
_shot = _shot + 1
goto "bigloop"

#exit
exit

I'll test it right away, thanks!

Put the _ranDir and _ranDia inside the loop too.

[Krieg]

I tried the script, but shells seemed to fall somewhere in the ocean.
I did put _ranDir and _ranDia in the loop as you suggested.

Ok.
I assumed the _pos is an object you refer to in the script and overlooked it not being there.

So put for example a game logic where you want the arty to drop and name it to something you like and instead of _pos use the name of the game logic in the script.

Or instead of typing the name into the script you can do something like:

Code: [Select]

_pos = _this select 0;
_shot = 0

#bigloop
?(_shot == 50) : goto "exit"

_randDia = random 150
_randDir = random 360
_shell = "Shell125" createVehicle [(getPos _pos select 0)+_randDia*sin(_randDir),(getPos _pos select 1)+_randDia*cos(_randDir),50+(random 50)]
_shot = _shot + 1
goto "bigloop"

#exit
exitThen you execute that script with [gamelogic name] exec "script.sqs"

[Krieg]

That works perfectly!
Thanks h-!

Two more questions:

When I tried executing a _pos from onMapSingeClick, it reported some error, but the script itself was too long so I was not able to read what kind of error it was. Is there any way to fix this?

Does random work with time delays (i.e. ~random 1)?

When using onMapSingleClick you need to do something like:

Code: [Select]

onMapSingleClick {[_pos] exec "script.sqs"}And then change the shell creation line to

Code: [Select]

_shell = "Shell125" createVehicle [(_pos select 0)+_randDia*sin(_randDir),(_pos select 1)+_randDia*cos(_randDir),50+(random 50)]
I'm not completely sure that works because it has been years since I have done anything with mapclick..

Does random work with time delays

Yes, you probably need to use it like this to avoid errors:
~(random 1)

Works perfectly! Thanks!
