Macro Recorder Emission From Rollout UI Actions

When performing a UI action from a scripted rollout, MAXScript disables the MacroRecorder.

To allow the code emission from UI actions modifying existing paramBlock parameters, the following context can be specified in 3ds Max 2013 and higher:

with macroRecorderEmitterEnabled <bool_expr> <expr>

When <bool_expr> evaluates to true , the MacroRecorder will be enabled and relevant changes to paramBlock parameters, as well as scene node creation, will trigger code emission. Creation arguments will not be recorded.

When <bool_expr> evaluates to false , or if the context is not specified at all, the expression will produce no Macro Recorder output.

NOTE:Other scene changes like object deletion, or calls to other functionality except for paramBlock changes will not produce Macro Recorder output.

EXAMPLE

rollout testMacroRecorderEmission "Test MRec Emission"
(
	local theSpheres = #()
	checkbox chk_emitMacroRecorderCode "Emit MacroRecorder Code"
	button btn_modifyRandomSphere "Modify Random Sphere Radius"
	
	on btn_modifyRandomSphere pressed do
	(
		with macroRecorderEmitterEnabled chk_emitMacroRecorderCode.checked 
		(
			theSpheres[random 1 theSpheres.count].radius = random 10 100
		)
	)
	on testMacroRecorderEmission open do
	(
		for y = 1 to 5 do 
			for x = 1 to 5 do
				append theSpheres (sphere radius:10 pos:[x*50,y*50,0])
	)
)
