does pop awaken work when collision response is to set to "stop"?

[angelous4x]

Hello,

I'm having a weird issue where I have just some particle colliding with a ground node, move to hit, and response to "stop" and "move to hit" checked on. However, when I use the pop awaken the "stopped" attribute goes back to 0, but none of the forces affect it. but the Velocities are updated in the geometry spreadsheet. not sure why that is. any ideas why?

seems like checking on "moke to hit" is the issue. in the documentation, it mentioned the 'move to hit' essentially does v@P = v@hitpos.  How do I change the @P not to equal the hitpos once it set to awaken?

just set popsolver->collision behavior->group to affect, so you know what i mean now, 

to "* ^on"

Hi Benyee, 

thanks for the responce, typed "*^on" in the popsolver->collision behavior->group to affect, but doesn't seem to work

The POP Awaken DOP is only modifying the "stopped" attribute while the rest of the hit condition/position attributes remain unchanged - you'll see this reflected in the Attribute Spreadsheet of your POP Geometry. 

If you disable the POP Solver'ss "Move to Hit" and set the behavior back to "Unchanged" to just get the hit detection, adding a POP Wrangle into the chain with

Quote

if (@hitnum > 0)
{
    @stopped = 1;
}   

Will freeze your particles where they collide and then release them to fly away as expected when they re-awaken

thank you Ryew, 

i did try to uncheck the move to hit options, but if I have a uneven collision surface it will be offset, I posted the same question on side effects forums, I got it working 

here is the link is ur curious.
