Hello, im trying to create a script or buy a script full perms that will poof when an avatar walks, its for a pair of shoes and id like the poofer to leave prints along the floor as the avatar walks. Any help would be appreciated im a total noob when it comes to scripts but again id appreciate any help or direction.

This should more or less do it for you.

default
{
on_rez (integer foo)
{
llResetScript();
}

state_entry()
{
llSetTimerEvent(0.1);
}

timer()
{
integer IsAvWalking = llGetAgentInfo (llGetOwner());
if (IsAvWalking & AGENT_WALKING)
{
llSay (0,"remove this line and replace with your particle system call";
}
}
}

Put the script into the shoe and replace the llSay() line with the particle system call that you want to trigger and you're good.
