Post information you feel is useful to others about the engine, algorithms, art and game-dev in general.

Tip:

As you populate a child GuiListBoxCtrl of a GuiScrollCtrl, they will both resize automatically. A child GuiDynamicCtrlArrayControl of a GuiScrollCtrl will not do this, however. A method for dealing with this is keeping a counter variable that will represent the Y extent of the GuiDynamicCtrlArrayControl. Increase the counter with each item that you add to the list. When all of the items are added, change the Y extent of the GuiDynamicCtrlArrayControl and call computeSizes() on the parent GuiScrollCtrl. This will scale the scroll bars properly.

If you want to be able to save the dynamic fields of a GUI object to a taml-file, don't forget to set
canSaveDynamicFields = true;
for the object.

If you only want to pick objects of the n:th scenelayer in a scene, you have to use the index n+1 in masking,
%objects = %scene.pickPoint( %worldPosition, "", %n+1, "any" );
I think this is illogical.

@Eero - Can you explain a little further? What is the range of n you are using?

The range of %n is [0, 31]. I guess there's an inconsistency somewhere in the engine, but I wasn't able to find it; counting layers begins from 0 onwards in one place and from 1 on in another?

I mislead myself on a false premise for hours. Here's the correction: the picking method interprets the integer representing the layer as a BITMASK. (I don't know if I should have got that from the word "mask"...)

This is a way that seems to work:
%objects = %scene.pickPoint( %worldPosition, "", addBitToMask(0, %n), "any" );
