[Closed] Wishlist for callbacks: Please list yours

Hey Chris (what’s up?),

Can I ask for a callback which returns true when say the user is double clicked in the viewport? If so, I will have to make a small list of callbacks which would be really useful.

Thanks man,

I think that callbacks for subobject operations would be nice, like:
when a sub object is selected (return bitarray of selection)
when a sub object is moved (no return)

and things along a similar vein.

Much more events about ANIMATIONS.
When a key has been

• moved
• deleted
• added.

MOUSE

• right click from mouse
• middle click from mouse
• mouse scroll
• button4 and button5 clicked
• mouse moved (it would be nice if it could also return the direction the mouse has been moved in).

As many events as possible about things happening on EDITABLE_POLY Object.

• extrude started/stopped
• bridge started/stopped
• chamfer started/stopped
• more like the above
• subobject level changed

Well write up your list and post them here.

Are you aware that a change handler will recognize sub-object selection changes, and transforms? For instance:

function OnSelectionChanged =
(
	print "in OnSelectionChanged"
	format "	Sub-Object-Level: % 
" subobjectLevel
)
function OnGeometryAltered =
(
	print "in OnGeometryAltered"
)

when select objects changes obj do
(
	print obj
	OnSelectionChanged()
)
when geometry objects changes obj do
(
	OnGeometryAltered()
)

Take an editable poly, select some faces and starting moving them around and you will see it.

However, I agree with you, that for consistency, perhaps there could be a callback to handle these situations.

I think callbacks for mouse clicks and key presses would be very useful, like: when the user double clicks, right clicks, presses C, etc. A callback that would return the SO the mouse is over (or closest for edges/verts), and the SO (left/right/middle) mouse button clicked on would be great too. Also a callback returning the SOs being moved by a relative and absolute coordinates.

I can think of some more later.

Thanks,

Yes, i know about that. But the change handler isn’t that much fun to work with. It’s also a broad callback for lots and lots of things.

A series of callbacks for use DURING rendering would be great. Right now it’s impossible to do update a scene per frame while rendering unless you do a messy workaround. I know that’s more to do with how max caches before render, but it would be nice.

A callback that registers when you’re typing in the maxscript window would also be wonderful!
