If owner touch then; if else, nothing; HOW?

What can I use to make it so something changes when only the owner touches it? Been looking around and cant quite find something right...

[original code]

touch_start(integer total_number)
{
if (llGetColor(ALL_SIDES) == <1.0,1.0,0.0>
{
llSetColor(<1.0,1.0,1.0>,ALL_SIDES);
}
[/original code]

[what i want]

touch_start(integer total_number)
{
if person who touched == owner
{
if (llGetColor(ALL_SIDES) == <1.0,1.0,0.0>
{
llSetColor(<1.0,1.0,1.0>,ALL_SIDES);
}
}
}

[/what i want]


Thanks in advance!

You need llGetOwner to find the owner of the object and llDetectedKey to findout who touched it

touch_start(integer total_number)
{
if (llGetOwner() == llDetectedKey(total_number))
{
if (llGetColor(ALL_SIDES) == <1.0,1.0,0.0> )
{
llSetColor(<1.0,1.0,1.0>,ALL_SIDES);
}
}
} 

well that was quick, thank you very much

This is broken... It should be :

touch_start(integer total_number)
{
if (llGetOwner() == llDetectedKey(total_number - 1))
{
if (llGetColor(ALL_SIDES) == <1.0,1.0,0.0> )
{
llSetColor(<1.0,1.0,1.0>,ALL_SIDES);
}
}
}

lol, I was in SL doing that very condition and realised that I'd got it wrong in the post. SO I popped back to correct.

As Ace says, my code is slighty broken.
