Maxscript need help: integer to frame

Sandeir · Apr 2011

hey,
i'm currently making a 'walkcycle-creator' maxscript
and i just faced my first big problem:
i can't find how i convert an integer into a frame

so i have this timespinner in which you can set the number of frame's for a walk-loop

so i would like to get the integer from the spinner and convert it into frames so i can use it in the slidertime to set keys.
here's the code i have so far

thanks in advance,
Sandeir

You probably just need to cast the vale as a time value.

timeValue = ( spinner.value as time )

hmm no sorry that doesn't seem to de the trick, but thanks anywhay,
because when my Timespinner value is 24 an i want to set a key at the 12th frame i would type "timeslider = (tijd/2)f" and ik give's an error

it's probably easy'er if i just add my code, sorry

rollout WalkcycleCreator "WalkcycleCreator" width:224 height:272

	spinner TijdSpinner "Timespinner" pos:[10,30] type: #integer width:200 height:44 range: [12, 36, 0]

You don't need the "f" when setting sliderTime. You can just say:

slidertime = (tijd/2)

If you run into a situation where you do need the integer as a frame number you can convert it using "as time"

slidertime = (tijd/2) as time

The trickier situation is converting a frame to an integer. For example,

60f as integer
--Result: 11520

(60f as integer)/ticksperframe
--Result: 60

For some reason, the result is in ticks and not frames. But if you divide by the global variable ticksperframe you get the number you are looking for. Luckily, just like slidertime accepts an integer, most things that require and integer can be fed a frame number.

it still doesn't do hat it's suppose to do

tijd = TijdSpinner.value
		animationRange = interval 0 12
		with animate on 
		(
			
			toolmode.coordsys #local
			slidertime = 0
			select $Bip001
			move $ [0, 0, -20]
			rotate $ (angleaxis 5 [0,1,0])
			rotate $ (angleaxis 20 [0,0,1])
			select $'Bip001 R Foot'
			--move $ [0, -30, 10]
			move $ [10,-40,10]
			rotate $ (angleaxis -20 [0,0,1])
			rotate $ (angleaxis -5 [0,1,0])
			rotate $ (angleaxis -30 [1,0,0])
			
			biped.SetSlidingKey $'Bip001 R Foot'

			slidertime = (tijd/2) as time
			select $Bip001
			move $ [0, 0, 10]
			select $'Bip001 R Foot'
			move $ [0, 50, 0]
			biped.SetSlidingKey $'Bip001 R Foot'
		)

it's suppose to set key at frame 6, but is doesn't

This is odd, but the problem is that you set the range for TijdSpinner to [12, 36, 0]. The last number 0 is the current value of the spinner even though it displays 12. You can just set the range to [12, 36, 12] and it works.

hey monster thanks that helped a lot !!!

my code looks like this at the moment:

rollout WalkcycleCreator "WalkcycleCreator" width:224 height:272
(
	spinner TijdSpinner "Timespinner" pos:[10,30] type: #integer width:200 height:44 range: [12, 36, 12]
	slider TypeSlider "small - normal - cartoony" pos:[20,100] width:200 height:44
	button btnCreate "Create" pos:[20,180] width:100 height:50
	
	
	global tijd = TijdSpinner.value
	
	on TijdSpinner changed value do
	(
		animationrange.start = 0
		animationrange.end = tijd as time
	)
	on btnCreate pressed do
	(
	framerate = 25
	--Create Biped---------------------------------------------------------------------
	Bip001 = biped.createNew 170  -90 [0, 0, 165] spineLinks: 2
	--------------------------------------------------------------------------------------
		
		typeAnimatie = TypeSlider.value
		--tijd = TijdSpinner.value
		print tijd
		with animate on 
		(
			--
			toolmode.coordsys #local
			slidertime = 0
			select $Bip001
			move $ [0, 0, -20]
			rotate $ (angleaxis 5 [0,1,0])
			rotate $ (angleaxis 20 [0,0,1])
			select $'Bip001 R Foot'
			--move $ [0, -30, 10]
			move $ [10,-40,10]
			rotate $ (angleaxis -20 [0,0,1])
			rotate $ (angleaxis -5 [0,1,0])
			rotate $ (angleaxis -30 [1,0,0])
			
			biped.SetSlidingKey $'Bip001 R Foot'

			slidertime = (tijd/2) as time
			select $Bip001
			move $ [0, 0, 10]
			select $'Bip001 R Foot'
			move $ [0, 50, 0]
			biped.SetSlidingKey $'Bip001 R Foot'
		)

I want to make from 'tijd' a global variable so i can change the animationrange when you turn the spinner but it give's this error "** system exception **"

Inside the rollout definition you can't actually execute code. You can only define the UI and what happens when you interact with the UI.

But, you can execute code once the rollout is created.

on WalkcycleCreator open do
(
global tijd = TijdSpinner.value
)

thanks monster, that was the missing link i guess

so here's my code up 'till now

rollout WalkcycleCreator "WalkcycleCreator" width:224 height:272
(
	spinner TijdSpinner "Timespinner" pos:[10,30] type: #integer width:200 height:44 range: [12, 36, 0]
	slider TypeSlider "small - normal - cartoony" pos:[20,100] type: #integer width:200 height:44 range: [0, 10, 5]
	button btnCreate "Create" pos:[20,180] width:100 height:50
	
	on WalkCycleCreator open do
	(
		global tijd = TijdSpinner.value
		global type = TypeSlider.value
	)
		on TijdSpinner changed value do
		(
		tijd = TijdSpinner.value
		animationrange.start = 0
		animationrange.end = tijd as time
		)
		on TypeSlider changed value do
		(
			type = TypeSlider.value	
			print type
		)
	on btnCreate pressed do
	(
		framerate = 25
		--Create Biped---------------------------------------------------------------------
		Bip001 = biped.createNew 170  -90 [0, 0, 165] spineLinks: 2
		--------------------------------------------------------------------------------------
		animationrange = interval animationrange.start animationrange.end
		typeAnimatie = TypeSlider.value
		--tijd = TijdSpinner.value
		print tijd
		with animate on 
		(
			--
			toolmode.coordsys #local
			slidertime = 0
			select $Bip001
			move $ [0, 0, -6]
			rotate $ (angleaxis 5 [0,1,0])
			rotate $ (angleaxis 20 [0,0,1])
			select $'Bip001 R Foot'
			
			move $ [10,-13,2]
			rotate $ (angleaxis -20 [0,0,1])
			rotate $ (angleaxis -5 [0,1,0])
			rotate $ (angleaxis -30 [1,0,0])
			biped.SetSlidingKey $'Bip001 R Foot'
			select $'Bip001 L Foot'
			move $ [0, 13, 2]
			rotate $ (angleaxis -20 [0,0,1])
			rotate $ (angleaxis 30 [1,0,0])

			slidertime = (tijd/4) as time
			select $Bip001
			move $ [0, 0, 10]
			select $'Bip001 R Foot'
			move $ [0, 50, 0]
			biped.SetSlidingKey $'Bip001 R Foot'
			
			
			
		)
		
	)

and also does someone has some great reference about scripting animation with a biped?
found dees : http://www.cgplusplus.com/online-reference/maxscript-reference/source/biped_maxscript_extensions.htm
but that's just the help

Maxscript need help: integer to frame
