Hello,

I am writing a script to detect when I collide one movie clip with another and add numbers to the score. I have the script working and it looks like this.

if (\_root.cone1.hitTest(\_root.car)) {  
numHit +=1;  
}

I want to increase the numer of items on the screen and thought I would try a for loop for a number of instances of the cone object ie  
for (i=0; i\<10; i++)  
{  
if (\_root.cone1.hitTest(\_root.car)) {  
numHit +=1;  
}  
}

within this i need to replace cone1 with and identifier based upon the value of i. How do I do this and what is the syntax required.

Thanks for any help

Solved it!!!

for (i=0; i\<10; i++){  
myCone = \_root[“cone”+i];  
if (myCone.hitTest(\_root.car)) {  
numHit +=1;  
}  
}

It works not sure if its the best way of doing it though

Yep, it’s the rigth way to do it. Good idea with the reference too 🙂 But you could declare it as a temporary variable (with “var”), as it is just used inside the loop.  
You could numHit++, by the way. It’s nicer :beam:

you could also put it all in one line (though its not really ‘nicer’ I dont think heh more confusing)

for (i=0; i\<10; i++) numHit += \_root[“cone”+i].hitTest(\_root.car);

I’m not used to that boolean trick you use, Sen, but why not?

A tiny bit clearer way could be, I guess

```auto
for (i=0; i<10; i++) _root["cone"+i].hitTest(_root.car) ? numHit++ : null ; 

```

no I imitated him 🙂

he gave a suggestion; I gave a suggestion (which wasnt based off his and made the code messier and less nice - nice is good though) 🙂

Ill belittle him now though

the ?: if else structure isnt really appropriate in replacing just an if statement as ?: relates to “if not one then another” - the null being an unnecessary addition. Instead it could be just

for (i=0; i\<10; i++) if (\_root[“cone”+i].hitTest(\_root.car)) numHit++;

which is actually better than my initial example because the addition is only executed when the hitTest is true and not for every loop of the for clause

but I still :love: ilyaslamasse emmensely  
:flower:  
[size=1]sorry lost[/size]

lol

[edit] That by the way is essensially what ilyaslamasse firs suggested with ++ just on onle line 🙂

sorry for posting here, i know it is not supposed to be posted here, but how can i get my footer up? Kirupa’s thread makes no sense, there is no link to Flash Footers at the top of any page… And if i post this in Help Forum, it will not be found  
:-\ sorry about the post
