declaration of variables in cycle

Hello…
since I can hardly declare… I’d like to know if there is a multiply declaration of variables i.e. in the cycle. It will save my time and lines :slight_smile:
Is there some alternative to this model(doesn? work of course :))

for i=1,14 do local variab..i=movieclip.newAnim{"pic1.png","pic2.png"}; myGroup:insert(variab..i); variab..i.x=200; variab..i.y=200+(i-1)\*40; end

is there some syntax which I can use instead of that “variab…i” or I have to declare variables one by one?

Hi,

your declaration won’t work. But as you have declared your variables inside the loop as local, you won’t see them outside the for loop anyway. I recomment to study LUA’s scoping rules.

So, if you don’t need to see the variables outside the loop, then just reuse one:

[lua]for i=1,14 do
local variab=movieclip.newAnim{“pic1.png”,“pic2.png”};
myGroup:insert(variab);
variab.x=200;
variab.y=200+(i-1)*40;
end[/lua]

Later you can get access to each movieclip by indexing the group:

[lua]for i=1,#myGroup do
myMC = myGroup[i]
myMC:play()
end[/lua]

Or if you need to have access to the single variables somehow, then use a table (which a group is too):

[lua]local myTable = {}
for i=1,14 do
myTable[i]=movieclip.newAnim{“pic1.png”,“pic2.png”};
myGroup:insert(myTable[i]);
myTable[i].x=200;
myTable[i].y=200+(i-1)*40;
end

for i=1,#myTable do
myMC = myTable[i]
myMC:play()
end[/lua]
