Oh, I see, I didn't notice that. I appreciate the help!

Graham’s script also added parentheses around the two SR1 etc size checks; this probably solved the issue.

I think the other issue was this code in the touch_start() event:

Code: Select all

                if (spin==3){
                    spin==0;
                }
I'm a little surprised that compiled even in SL - the "spin==0" part should be "spin=0" (assignment, not comparison). Graham's version fixed that.

That's assuming the backboard prim is link number 11, which might not be the case if the object has been relinked.
This reminds me of a long standing, allbeit fairly minor, item on my features wishlist: A way to resort the linking order without having to unlink and carefully select each item one by one.

if (llDetectedLinkNumber(0)==11&running==FALSE) // touching backboard

As mentioned by another, this is problematic coding, because link order can easily change. There are two better ways to do this, both similar. Test for either the name of the prim or the description (and then make sure that prim has a specific name or description. You may have to add one). To do this use llGetLinkPrimitiveParams() and the PRIM_NAME or PRIM_DESCparameter.

Semi-code example:
if( name_of_linked_prim == "this name" & running==FALSE) {do this;}

Code example:

if(llGetLinkPrimitiveParams(linknum,[PRIM_NAME])=="specname"...


(I think all that is correct. Doing this on the fly so if syntax is incorrect somewhere, someone feel free to point it out.) :)

Tess, lol I did have trouble with this. I naturally thought since there were 12 prims that if I linked it second to last (with the root prim being last) that it would turn out to be link 11. But that wasn't the way it turned out, sometimes it came out to be link 2 and sometimes it came out to be link 12. I ended up linking it 3rd to last which made it link 11. It took a lot of trial and error though, I'm lucky it was only 12 prims! :)

Thanks John, that's good to know. I am not knowledgeable about scripting. All help is appreciated! I'm sure there is a reason why sometimes == is used and sometimes = is used but it's way over my head.

Thank you Snoots, Yes, I'm sure that's a much easier way. I haven't come across a lot of scripts that used the link number. I think her scripts are old so I imagine that's an old way of doing things. Most of the scripts I've used use the name but I have encountered a few that use the description (mostly those were teleport scripts if memory serves me). I appreciate the help!

The next one that isn't working is her High Striker. There are 3 prims:

1) *Steam Fair* High Striker 4.23 (3 prims) [root prim]
2) Object [numbers on face]
3) weight [the weight that goes up and down]

Here is the only script that's in it [named High Striker] and it's in the root prim in SL - once again there is the "#" that is a problem, I tried to change it from "weight_prim#" to "weight_primNum" and "weight_prim_Num" and neither worked and gave error messages.

Also, "S0 = (float)prim_pos.z ;" created problems.

Code: Select all

// Strength Test Game Control, in root prim, controlling weight prim in linkset 
    //global variables
    // physics parameters
float V0 = 0.0 ; // initial velocity
float A = 0.0 ; //  acceleration (positive is upwards) gravity= -9.8
float S0 = 0.0 ; // initial distance from point of rest
float S = 0.0;   //vertical displacement from rest point ;

integer weight_prim# ; // check actual prim in linkset
key id ;
string name =""; // player name
string prim_name="weight" ;
integer win=0 ; 
integer Swing_power = 0 ;
integer i ; //incremental counter
integer total_number;

float interval = 10.0 ; //time period for swing
integer count ; // tally touches during swing

Thanks for your help, Snoot. If it's full of bugs I should probably just not use it since I'm not a scripter and wouldn't be able to find all of the problems. I appreciate the explanation about the == Much of it is above my head. You seem to know a lot about scripting.

For the Arcadia script, # cannot be used as a variable identifier. In some languages # means 'integer'. If that is found, remove all instances of that addition to the variable name and make sure the variable has already been declared as an integer (or whatever numbering method it's replacing.

Line 95 & 100 had to be changed to properly declare variable.

The rest of the script is full of bugs that would require some time to debug.

Regarding what you asked about the difference between == and = and =....

Within a decision statement (EXAMPLE: if ( a == b && c = TRUE){ D=9;}

== is a direct comparison: if(a == b) // getting this wrong and using just = is the rue of many a coder.
= is a boolean comparison (true/false, positive/negative) ---- be sure to not confuse == with =. == compares values. = compares boolean logic.
Outside a decision statement, = is an assignment. A=B; C=5; Avatar="Fred"; Scripting="Lame" etc ;)

Those are the 3 ways those symbols are used.
