Hi i am making a card game of 52 cards, made from skinmesh imposter i need to detect when a card is ontop of another card, when one card is within threshold of other card they will bothe be removed/hidden, the problem is i need to check all 52 cards against eachothers position an hide two cards if they are within the threshold, the problem is i had to make the long code so that say card 1 is not checked against itself in the loop as then it will hide itself even when another card is not near it, the loop works but does lag a bit soi wondered if it could be made more eficient but still not check the cards agaist itself as it will be hiden straight away, so say when i check the vectorlength of card 1 agaist the array of all cards it checks card 0 and then cards 2 to 52 and not card 1 as it will hide itself, so what happens is when it checks cardlocation against cardlocation it will check card 0 against all cartds including card 0 and 1 against 1 etc then it hides the card when it checks against itself.

hope this explains as i had help with translation as english not first language

If your really picky and want the absolute fastest code, go with 20 lines and ugly  large looking scripts.

If you don't mind loosing a few milliseconds here or there and want neat and tidy looking code, use loops.

The real answer here can only be supplied Fernando because he has access to 3drads internals, and would know more on what exact process is going on and which would be the fastest.

Generally, my conclusion above i believe is the proper answer for scripting in general.

Read on for my explanation of my above view.



i know what your asking, i wondered years ago about this too.

My 3 cents worth.

When you do looping, your repeating the same piece of code, lets say, 20 times.

if you instead print out that code as individual statement lines, you would have 20 lines of script, instead of a loop with maybe 2 to 5 lines.

Technically, i believe 20 lines would be more efficient, simply because, looping adds a few more lines to the process, plus 1 or 2 variables as well.

So... the straight 20 lines of code is still processed 20 times by both process's.

The looping is probably a few milliseconds slower due to the extra loop code processed 20 times too.

But the loop also looks much neater and makes your script easier over all to work with.

it seems like you've got the logic down pat,  so there's really no decision to be made here... use the method Roberto suggested... (with a slight modification, because i never saw where the location variables are set)...

for (int i=0; i<imposters; i++)
{
   iObjectImposterGet(OBJ_X,intImposterNum,QuaternionVar,Vector3Var);
   if (iVectorLength(CardLocation[i]-refCardLocation)<10) HideCard(i);
}
(assumes HideCard() is a function)


you're not writing assembler code... you don't need the longwinded version
