Hi,

Is there a way to use an entire array as an argument list?

I need some way of doing this:
iArr[] init 10
event_i "i", 1, 0, 1, iArr

Actually, what I'm trying to achieve is to generate a table using an 
array for its arguments. The problem is that I don't know the size of 
the array until run-time.

Thanks.

You could do:

iArr[] init 10
iArr fillarray 6, 6, 6, 6, 6, 6, 6, 6, 6, 6
event_i "i", 1, 0, 1, iArr[0], iArr[1], iArr[2], iArr[3], iArr[4], iArr[5], iArr[6], iArr[7], iArr[8], iArr[9]

Doing variable argument count can be pain, but you would have to loop. If you dont want to initialize an Array to a fixed size, you could use Joachim Heinz's string arrays, then it's easy to just make an opcode that will count the number of values in an array and make an event function with the amount of parameters nedded (or requested for).

Maybe this is helpful, you have this opcode at both i- and k- rate.

You will have to make a if tree or loop_lt loop. But an ugly if tree yould solve it easily, something like;

iparm count iArray

if iparm == 1 then
 event_i "i", 1, 0, 1, iArr[0]

elseif iparm == 2 then
 event_i "i", 1, 0, 1, iArr[0], iArr[1]
elseif iparm == 3 then
 event_i "i", 1, 0, 1, iArr[0], iArr[1], iArr[2]

.....etc...

endif

you have to know the size of the string array or normal array, where are you filling the array, with score event, orchestra? Whereever the source of the array is coming from, you should be able to find a way to count how many arguments you are providing for the parameters in the score event.

Hi Hlöðver,

I've just implemented what you propose using a fixed size array. I'm already using StrayGetNum. But I was wondering if there was a way to write an event_i statement that has a variable (known at run-time) argument list. I have not been able to solve that.

What I mean is I've my variable-sized array already filled with the correct numbers, but how can I create an event_i that takes that information. Fixed-size arrays/arguments seems to be the only way. Isn't it?

hi guillermo -

if i understand correctly, you have a string first.  wouldn't it be 
better to send and receive this string (could be done with the scoreline 
opcode) instead of an array?

Hi Joachim.

I think you are right! I haven't thought about using scoreline_i. I've 
actually never used it before. I'll try that right now.

Thank you.
