some kind of vendor maybe?

i want to make and object that will attach somthing to me when i activate it,i have no idea how to do this ,i have some very basic scripting knowldge ,so if anyone has an example script i could have or any tips would be helpful?

You can only attach the obejct in which the prim is located.

default 
{ 
    touch_start(integer total_number) 
    { 	
        // ask for permission to attach
        llRequestPermissions(llDetectedKey(0), PERMISSION_ATTACH); 
    }
    
    run_time_permissions(integer perm) 
    { 
        if (perm & PERMISSION_ATTACH)         
        { 
            llAttachToAvatar(ATTACH_LHAND);   
        }           
    } 
}

thank you for that but is there anyway i could attach i second object inside the prim with the script in it?

Not directly, you woudl need to rez teh second object and then have it attach itself.
However that may not be necessary, you could just have teh second object already attached but with its alpha set to 0 so that its invisible an dthen just chaneg its alpha to 1 to make it visible.

yes i thoght of doing that but ,would it not lag?
