bulletphysics - How to achieve maximum simulation accuracy in Bullet? -


i'm simulating rope rope collision in bullet , i'd accurate possible. don't need simulation real-time. rope consists of rigid bodies connected using constraints(e.g. btconetwistconstraint).

which settings need tweak simulation become more realistic , accurate?

from experiments decreasing 3rd parameter 1/300 gives additional accuracy. 

gdynamicsworld->stepsimulation(simulation_step_time, 1, 1.0f/60.0f);

also increasing solver iterations count helps bit:

btcontactsolverinfo& info = dynamicsworld->getsolverinfo(); info.m_numiterations = 50;

there videos people simulate thousands of bodies in blender. i'd achieve similar effect in c++ app.

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
