setting up box2d with project-creator script?

cocos2d-x C++
#1

Hi, is it possible to use the multiplatform project-creator.py script to include Box2d? I’ve seen this tutorial linked a lot: http://bold-it.com/ios/cocos2d-x-box2d-iosandroid-hybrid-tutorial/ but the create-android-project script it uses is deprecated/gone right?

If I have to add Box2d it manually, can someone go through each step please? Maybe cocosdenshion as well if its similar process? It took me a week to setup cocos2d properly the first time and adding libraries and stuff gets really confusing for me :frowning:

i have done this manually - you need to

  1. search for CC_ENABLE_CHIPMUNK_INTEGRATION=1 and change to CC_ENABLE_BOX2D_INTEGRATION=1 in the preprocessor definitions
  2. set $(COCOS_ROOT)/external/Box2D/ in the header search path. for your app.

thanks, but which files are these changes in? And i don’t have to copy any folders over or set up libraries through Eclipse at all?

#4

in application folder proj.android/jni/Android.mk, cocos/2d/Android.mk and extensions/Android.mk

#5

I think you should set the include path to $(COCOS_ROOT)/external/ as the Box2d includes are of the form #include “Box2D/Box2D.h”
Hope this helps…

hi are you guys using 2.2? I am having trouble box2d to compile … I have made changes to android.mk file and still it doesnt work…

#7

I made a mistake in my comment earlier… set an entry in your include path to $(COCOS2DX_ROOT)/external
I am using 2.2.1

#8

oh ok. do I have to make changes to all the .mk files or just the one in the jni folder?

#9

What compile errors do you get? There could be many reasons for your problems…

#10

The game was building fine before I included box2d

basically anything that involved box2d it says it cant resolve desnsity, friciton, shape, createfixture.
