To solve a problem it is nice to know what the problem is.

You have made very clear what you want to happen, but not what is happening.

So the question remains, when your program is running, what is the text showing?

I understand it's not showing what you want it to show, but to know where the problem is, it is necessary to know what the problem is exactly.

Arm set angle towards position x: mouse.x - y: mouse.y

for this to work the origin of your arm should be on the turning point.

Thanks.. I know from my own experiences how helpful these forums can be.. I've learned most of the basics on here myself..

I'm on here almost every day, mostly inbetween creating my own stuff.. Helping others is a good way for taking a break from my own programming..

I'll see if I have time tomorrow to whip up another example for you..

I read somewhere Darklinki uses smaato for their mobile advertisements.

Maybe something to look into?

How do you create the vector shape?

C2 doesn't support vectors without 3rd party plug-ins as far as I know..

Would this work?

system compare 2 values : textbox.txt is not ""

First question:

Is everything in your game physics?

If yes, using physics on the boulder will work, if no, you should try to fake the physics part with events, because physics doesn't mix well with other behaviours.

Set the origin of the line sprite to the left.

set position to sprite1.x,sprite1.y

set width to distance(sprite1.x,sprite1.y,sprite2.x,sprite2.y)

set height to 2(or 3, or 4, or whatever height you want)

set angle to angle(sprite1.x,sprite1.y,sprite2.x,sprite2.y)

There are ways to do this with even less events, but I made the events so they can be easily understood.

This example would actually work just as good with scrollto-behaviour, but the big advantage of the scrollto action is that it's easier to handle through events. It doesn't have to be every tick. Also, you don't have to use an object to scroll to, it could just be done with coordinates..

Instead of using the scrollto behaviour in this case it's probably much better to use the system scrollto action, setting up events and conditions for when to scroll and when not.

FAQ

Give the object an instance variable and add conditions to your events.

if variable is movement 1 - select your actions

if variable is movement 2 - select other actions
