Animation without actuator

Hi guys,I’m looking for help with the following issue: I wanna make animations employing scripting only without “Action” actuator. But there is a catch – I’m unable to stop this animation from inside a script before i start the next one on a layer.Using the actuator, it might look light this:

# start
if own ['prop'] ==1:


But without the actuator, it seems to be possible to stop the whole layer only:

if key_w == press:
    sce.objects['arm'].playAction('act1', 1, 40, layer=1, priority=0, blendin=5, play_mode=1, layer_weight=0.0, ipo_flags=0, speed=1.0, blend_mode=5)


Due to this I can’t use more than a single animation on a layer, and, as such, mix animations. Do you have any ideas on how to stop a specific animation?

P.S. All animations are using “loop stop” playback mode.
