Idiomatic way of sticking pics on a glass pane, and apply a transformation to the whole pane?

[Baldvin Kovacs]

I wonder if it is possible to attach pics to some sort of an abstraction like a glass pane, and move the pane as a whole?

A use case would be to have ~ a few hundred or a few thousand small objects forming the background, and let the whole background move, giving the illusion of the player moving in a larger-than-screen world.

One way is to draw the background as a single Picture, but then collision detection doesn't tell which little object did we collide. So I wonder if there's a version of, say, GPics where a translation can be applied to the whole thing in an efficient manner.

Thanks,

I found "scroll" for the canvas, which is probably one of the answers to my question.  (Using scroll I can simulate moving the background, I just need to move the non-background items to the opposite direction).

I am still interested though if there's some way to have several glass panes. Probably not, which is OK, I'm just curious if there's some features that I've missed while reading the code.

Ah, never mind - I found that BasePicList mixes in CorePicOps. Sorry for the noise.

No worries. Happy hacking.

PS. If you want to contribute a Hungarian translation, instructions are available here: https://bitbucket.org/lalit_pant/kojo/wiki/Kojo%20Localization
