A car with random or sequential color

Hi, I added a respawning trailer to Tiny Town and I want it to have different color every respawn. How can i acomplish that?

I tried this way:

Code:

...
COUNTER col = 6
...
LEVELSTART
...
SET col = ( col + 1 )
tr = CREATE_CAR ( 61.45 , 196.5  ) col 180 TRUKCONT END  //here is an error, if there is a number instead of "col" it compiles well
...

...but compiler throws an error.
How can I give a car random or sequential color?

You can't do it that way since the limited compiler requires a constant integer and won't allow a variable/counter.

You'd have to have one create_car command for every color you want to select from.

Too bad... I'll make the location of respawn sequential also then!
Thanks.

Coordinates and many other values also need to be constants.

Yes, but it's not a problem since I must write multiple create_car lines anyway.

BTW, can I set a counter to random value somehow?

There is no Random function in GTA2 but you can do a workarround (a modulo operation)

Code:

   SET temp = ( rand / 33 )
   SET temp = ( temp * 33 )
   SET surp_sel= ( rand - temp )

33 is the maximum random value

rand is a counter that is increased every WHILE_EXEC cycle and reset on pseudo random events.
It is important that it is a value that is different in every game and that the seed(rand) happens more often than event(surp_sel) otherwise you could get a repeating pattern.
If you use the same seed for multiple events ensure that the max values do not have a common divisor otherwise you will have correlations.

You can look how it works on BC Awkward Cargo
