ios - SKSpriteKit how to control Impulse or Force speed? -

hi guys want apply slow motion in upward direction,

what confused, when applyimpulse

[self.physicsbody applyimpulse:cgvectormake(0, 60)];

it applyimpulse required speed measure velocity mass , other physics things

what need applyimpulse controlling speed of impluse applied on object on impulse beingness applied.

i tried set self.speed got no success, how 1 can accomplish desired impluse or forcefulness on sprite controlling on speed.

are there properties should set skspritenode before applying impulse,

or thing else? suggestion or thoughts appreciated

thanks

the speed property of sknode skactions, speed property of skphysicsworld want tweak accomplish physics in slow motion.

it says next in documentation speed property of skphysicsworld

the default value 1.0, means simulation runs @ normal speed. value other default changes rate @ time passes in physics simulation. example, speed value of 2.0 indicates time in physics simulation passes twice fast scene’s simulation time. value of 0.0 pauses physics simulation.

access within skscene subclass this-

self.physicsworld.speed = 0.5; // half speed (slow motion)

ios skspritenode

html - Submenu setup with jquery and effect 'fold' - i want open submenu jquery effect fold, problem if user "hover effect" fast menu remain open, how can avoid this, jquery code is: $('ul.mainmenu li').hover( function() { $(this).children('ul').show('fold', 570); }, function() { $(this).children('ul').hide('fold', 500); } ); my jsfiddle link is: http://jsfiddle.net/9wkbf/ updated fiddle the reason behind problem is, first event $(this).children('ul').show('fold', 570); queued , until completes, sec animation not start. the next snippet can workaround $('ul.mainmenu > li').hover( function() { $(this).children('ul').show('fold', 570); }, function() { $('ul:not(.mainmenu)').hide('fold', 500); } ); *important note : work current scenario. jquery html css
