Example with no container
In this capx I have to do the picking manually and store UID values in instance variables to be able to link a "Head" to a "Body".Example with container
In this capx, no need to store UID values, the contained "Head" is automatically picked. Same goes for "Body" when the "main picked object" is a contained "Head".
For both projects: cursor over the body (colored big square) will modify the "attached" "Head"'s opacity.
Cursor over the "Head" (small black square) will display in the text the value of the "attached" "Body" "Color" instance variable value.
The effect here can be considered as "minor" but actually helps a lot with picking and possibly a lot of new comers will find the using curve of Construct 2 even friendlier.
