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 :s
so i have this timespinner in which you can set the number of frame's for a walk-loop
wcci.jpg
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. 
    1. 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 :s
    it's probably easy'er if i just add my code, sorry

    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 :s
    1. tijd = TijdSpinner.value
    2. 		animationRange = interval 0 12
    3. 		with animate on 
    4. 		(
    5. 			
    6. 			toolmode.coordsys #local
    7. 			slidertime = 0
    8. 			select $Bip001
    9. 			move $ [0, 0, -20]
    10. 			rotate $ (angleaxis 5 [0,1,0])
    11. 			rotate $ (angleaxis 20 [0,0,1])
    12. 			select $'Bip001 R Foot'
    13. 			--move $ [0, -30, 10]
    14. 			move $ [10,-40,10]
    15. 			rotate $ (angleaxis -20 [0,0,1])
    16. 			rotate $ (angleaxis -5 [0,1,0])
    17. 			rotate $ (angleaxis -30 [1,0,0])
    18. 			
    19. 			biped.SetSlidingKey $'Bip001 R Foot'
    20.  
    21. 			slidertime = (tijd/2) as time
    22. 			select $Bip001
    23. 			move $ [0, 0, 10]
    24. 			select $'Bip001 R Foot'
    25. 			move $ [0, 50, 0]
    26. 			biped.SetSlidingKey $'Bip001 R Foot'
    27. 		)

    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: 
    1. rollout WalkcycleCreator "WalkcycleCreator" width:224 height:272
    2. (
    3. 	spinner TijdSpinner "Timespinner" pos:[10,30] type: #integer width:200 height:44 range: [12, 36, 12]
    4. 	slider TypeSlider "small - normal - cartoony" pos:[20,100] width:200 height:44
    5. 	button btnCreate "Create" pos:[20,180] width:100 height:50
    6. 	
    7. 	
    8. 	global tijd = TijdSpinner.value
    9. 	
    10. 	on TijdSpinner changed value do
    11. 	(
    12. 		animationrange.start = 0
    13. 		animationrange.end = tijd as time
    14. 	)
    15. 	on btnCreate pressed do
    16. 	(
    17. 	framerate = 25

    49. 		)
    50. 		
    51. 	) 
    52. 	
    53. 	
    54. 		
    55. )
    56. --1) create biped
    57. --2) kies type (slider)
    58. --3) kies lengte (aka snelheid)
    59.  
    60.  
    61. CreateDialog WalkcycleCreator 
    62. --addRollout WalkcycleCreator

    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
    )

    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
