Hi quick question, in my current project I have a number of objects, each object contains the field Field image:Timage. which is the image data I use to draw the object. In the game each object uses 1 of 5 different images, so I am thinking rather than store the image data in each object I should be storing a pointer to the image data in each object? Thanks

What you are doing is effectively storing a pointer. All Blitz types are pointers to structures, so you only have to load an image once and you can have thousands of objects referencing it.

On the same kind of topic. Just tried out this code to explain something to myself: Type TSquare Field test:TBall EndType Local square:TSquare square= New TSquare Type TBall Field one:Int Field two:Int EndType DebugStop Local ball:Tball ball = New tball ball.one=3 square.test=ball square.test.one=6 Am I right in thinking that square.test is a pointer to ball? As the line square.test.one=6 changes the value of ball.one?

yes Type TSquare Field test:TBall EndType Local square:TSquare square= New TSquare Type TBall Field one:Int Field two:Int EndType DebugStop Local ball:Tball ball = New tball ball.one=3 print ball.one square.test=ball square.test.one=6 print ball.one run this
