I'm not sure exactly what you mean but you could use the expression:

choose(string1,string2,string3,...)

which will randomly return one of the strings

Does the error message say anything else?

I had a similar problem after a crash, where certain images couldn't be located.

I fixed it by opening the .capx in winrar and renaming image files :\

dunno if it's the same for you though.

You're using a 'step' behaviour plugin which means anyone without that plugin can't open your .capx

Just letting you know.

I gave Orange an instance variable

People have been saying they can't download from my dropbox.. if that's the case for you, then try in firefox, otherwise I'll just write down what I did here.

If you do decide to use the mouse I think the best way to do it would be to make the helicopter move simply camera-relative.. (where pressing up/down/left/right will always move the helicopter in that direction relative to the screen, regardless of the helicopters angle)

Also, you can smooth out and limit the rotational speed in a similar way you smooth out directions and limit their move speed.

Instead of setting the heli's angle to the mouse, set a variable 'targetangle' to the mouse... and have the heli.angle move towards that gradually using one of ..many.. methods..

hmm not sure If i know what you mean..

just to check, you are aware that the helicopter faces the direction of the mouse, right?

wut.. :S can anyone else try the link and confirm that?

Zephlon, try increasing the buttons 'linear damping' quite a lot. All this does is slow the objects velocity over the time.

You could try changing it from 'continuous' to 'one-shot' in the particle properties.

And have it create a new particles object every 0.05 seconds or something. Or every x seconds, where x can be proportional to the objects speed.

another thing that you may find useful is clamp() expression where you can set minimum and maximum limits for any value.

There are manual entries for this if you have a look..

You need to use the scrollx and scrolly system actions

To simply pin the scroll position onto an object you just have:

every tick: scroll to position: object.x, object.y

It might also help to enable Unbounded scrolling in the project properties

Reverse the conditions so that number=2 is above Pick nearest.

In short:

for x position you need to refer to Cos(heli.angle)

and for y position: Sin(heli.angle)

Sin and Cos basically generate a number between 1 and -1 depending on the angle given.
