object Movement

ok, i've look through this forum and the wiki several time and im afraid im just thick

heres what i want,

a script to keep an object moving forward, unless i hit something, in which case go back a bit, turning for a bit, then continue forward.

you know the one, all toy robots and maze-solvy things have it

ive tried and tried , but as LSL novice, i havent even got a clue about the moving, let alone the logic.

please can someone help me.

thanks.

Here's an example (I cant provide more help atm, kinda short on time):

float SPEED = 10;
    collision_start(integer numColliders) {
        // Vector pointing from this object to the object 
        // being collided with. You can think of it like an arrow.
        vector offset = llDetectedPos(0) - llGetPos();
        
        offset = llVecNorm(offset); // Normalize, we dont care about
        // How "big" the arrow is (magnitude), just the way its pointing.
        
        // Reverse the direction of the vector, making 
        // it point away from the object being collided with.
        offset *= -1;
        
        // Make the arrow "flat", we only want it to affect this object
        // on the x and y axes.
        // We dont want to change the object's height.
        offset.z = 0;
        // of course, now it wont help us when colliding with ceilings
        // comment the above line out if you do want it to.
        
        // Push the object in the direction of the arrow.
        // We subtract the current velocity, because
        // the collision would have already flung the object with
        // some force. The subtraction makes it so that the only
        // velocity the object has is due to the impulse we apply here.
        llApplyImpulse((offset * speed * llGetMass()) - llGetVel(), FALSE);
    }
}

thanks, will give it a try
