Grapple Gun

Was wondering, if anyone could get/make a copy of a script that allows you to shoot and object in 1st person view and , when the object collides with an av, ora brush of any kind,
it pulls you. A basic grapple gun... Me and my friend have attempted this so many times, and we are completely clueless. So if anyone out there wouldnt mind helping us.. PLZ DO SO!!!.
There will be a money reward !

The projectile should use 'llSetStatus()' to turn physics off as a result of a collision event. It should then shout its location. The attached weapon should listen (it can listen only to the key of the rezzed object) and do an 'llMoveToTarget()' to pull the avatar along when it hears the location. Particles with a target key might be nice for, "attaching," the two. Use a large random negative number for the channel to use and pass it to the rezzed object as its start parameter.

NOTE: You might want to have a method of turning off the movement (a quick chat or use of the control keys to trigger a 'llStopMoveToTarget()').

Oh. It would aso be considerate to have the projectile 'llDie()' within a reasonable time (maybe even right afterward) of hitting the target, so you don't leave a bunch of hooks floating around.

it already exists and i have one.. it was a freebie..dont remember the name but i shoot it and it grabs an avi and starts yelling "com here youuu" and drags the avi on the floor and reels em in like a fish lol.....

im kinda partial to the acme anvil dropper myself lol

Oh. I thought the original poster was talking about something that can be used to drag oneself to the target, not the other way around.

im not talking about that grapple hook that brings av's to u i mean u 2 it!

I created one the other day ^^ it's derived from the ExampleGun, so the code's not great, but anyway:

Your gun must be designed to held like a bazooka, and must be a physical object.


script in the gun:

// Make sure these are right
string gBulletName = "hook";
float gBulletSpeed = 100.0;

// use a hold anim, you'll go
// into the aim anim automatically when entering mouselook
string gAnim = "hold_r_bazooka";
string gGripMessage = "the hookshot is designed for the right hand only";
integer gGrip = ATTACH_RHAND;
integer gEnableBullet;
integer gEnableSound;
integer gArmed;
integer privateChannel = 2022;
vector gAimOffset;
vector gAimOffsetConstant = <0.0, 0.0, 1.0>;
vector target;

say(string message)
{
llOwnerSay(message);
}

getPerms()
{
integer perms = llGetPermissions()
| PERMISSION_TAKE_CONTROLS
| PERMISSION_TRIGGER_ANIMATION
| PERMISSION_ATTACH;
llRequestPermissions(llGetOwner(), perms);
}

verifyInventory()
{
if (llGetInventoryKey(gBulletName) != NULL_KEY) {
gEnableBullet = TRUE;
} else {
gEnableBullet = FALSE;
say("Hook not found: " + gBulletName + ". Please add to inventory.";
}
}

arm() {
integer perm = PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION;
if ((llGetPermissions() & perm) != perm ) {
getPerms();
} else {
llTakeControls(CONTROL_ML_LBUTTON, TRUE, FALSE);
llStartAnimation(gAnim);
gArmed = TRUE;
}
}

disarm() {
llStopAnimation(gAnim);
llReleaseControls();
gArmed = FALSE;
}


default
{
state_entry()
{
verifyInventory();
llListen(privateChannel, gBulletName, "", "";
}

touch_start(integer count)
{
if (llDetectedKey(0) != llGetOwner()) {
return;
} else if (!llGetAttached()) {
getPerms();
} else if (gArmed) {
disarm();
} else {
arm();
}
}

run_time_permissions(integer perms)
{
if (perms & (PERMISSION_TAKE_CONTROLS
| PERMISSION_TRIGGER_ANIMATION
| PERMISSION_ATTACH)) {
if (!llGetAttached()) {
llAttachToAvatar(gGrip);
} else if (llGetAttached() != gGrip) {
say(gGripMessage);
llDetachFromAvatar();
} else {
verifyInventory();
arm();
}
} else {
say("insufficient permissions";
if (llGetAttached()) llDetachFromAvatar();
}
}

attach(key avatar)
{
if (avatar != NULL_KEY) {
// attaching
vector size = llGetAgentSize(avatar);
gAimOffset = gAimOffsetConstant;
gAimOffset.z *= size.z / 2.0;
getPerms();
} else {
// detaching
if (gArmed) disarm();
}
}

control(key avatar, integer levels, integer edges)
{
// mouse press
if ((levels & CONTROL_ML_LBUTTON) && (edges & CONTROL_ML_LBUTTON)) {
}

// mouse release
if (!(levels & CONTROL_ML_LBUTTON) && (edges & CONTROL_ML_LBUTTON)) {
rotation rot = llGetRot();
vector aim = llRot2Fwd(rot);
vector pos = llGetPos() + gAimOffset + (aim * 1.0);
llRezObject(gBulletName, pos, aim * gBulletSpeed, rot, privateChannel);
}

// mouse down
if ((levels & CONTROL_ML_LBUTTON) && !(edges & CONTROL_ML_LBUTTON)) {
}
}

listen(integer channel, string name, key id, string message)
{
target = (vector)message;
vector here = llGetPos();
llMoveToTarget(target, 1);
llSetTimerEvent(2);
}

timer()
{
llStopMoveToTarget();
llSetTimerEvent(0);
}
}





And in the bullet itself:

float gTimeToDie = 20.0;
integer reply_channel;
shoutPos()
{
string position = (string)llGetPos();
llShout(reply_channel, position); //report vector back to hookshot
}

default
{
state_entry()
{
llSetPrimitiveParams([PRIM_TEMP_ON_REZ, TRUE]); // unreliable
llSetStatus(STATUS_PHYSICS | STATUS_DIE_AT_EDGE, TRUE);
//llSetBuoyancy(1.0); // uncomment for slow bullets
}

on_rez(integer start_param)
{
if (!start_param) return;
reply_channel = start_param;
llCollisionFilter("", llGetOwner(), FALSE);
llSetDamage(0);
llCollisionSound("", 1.0); // cancel default sound
llSetTimerEvent(gTimeToDie);
}

collision_start(integer count)
{
shoutPos();
llDie();
}

land_collision_start(vector pos) {
shoutPos();
llDie();
}

timer()
{
llDie();
}
}
