There is a bit of a discussion here about structs and memory allocation which Vec is:

http://monkey2.monkey-x.com/forums/topic/collision-module-and-performance

So it might be ok?

I could also change it to create the Vec2f on creation of the object and update X,Y before returning rather than generating a new one each call.

[Update: Ran it both ways for 10mins and the Memory Manager crept up a couple of meg at the start and was stable after that – so no real issue by the looks.]

Thanks.

Nice!

[Matthew SmithParticipant]

Haha! Needs the flashing loader! Miss lots of stuff from the good old days but not that one.

Is that a Pi 3 Simon?

[Matthew SmithParticipant]

Why not! Thanks!

[Matthew SmithParticipant]

Debugger will be great! Thanks for the update.

[Matthew SmithParticipant]

Ok – thanks Mark!

@therevills

Thanks for your response – yeah would be a nice to have! But no probs.

C# has a similar option using both this (Self) and base (Super):

Monkey

class Sprite { public Sprite(float x, float y) : this(x, y, 3) { } public Sprite(float x, float y, int lives) { } }

1 2 3 4 5 6 7 8 9 10

class Sprite {   public Sprite(float x, float y) : this(x, y, 3)   {   }   public Sprite(float x, float y, int lives)   {   } }

[Matthew SmithParticipant]

Ah – see that now! Doh! Thanks Mark!

[Matthew SmithParticipant]

Woops! Too much c# for me ATM! Trying to find some time to have a play – work and family a bit busy currently!

Great to see you too buddy! Hope all well in your part of the world!

Sorry how do we do the code snippets?

Found it – need to go into the Text option and click Crayon.

Wiebo,

When your initialising your Singleton your also not storing your initialised instance:

Monkey

If Not _instance Then Return New EntityManager

1	If Not _instance Then Return New EntityManager

should be

Monkey

If Not _instance Then _instance = New EntityManager

1	If Not _instance Then _instance = New EntityManager

So in this instance the object may be Null anyway causing the exception.

[Matthew SmithParticipant]

Thanks Mark – will take a look!
