box2dLights

[Magnesus]

Solved! I realised what is happening - the old Spine JAR and box2DLight JAR are expecting a method set(float r, float g, float b, float a) in libGDX Color class that returns void while in new libGDX it returns Color. Function set(Color c) works because it was already returning Color. We just need to use the newest source projects in both cases because both projects don't build new JAR files apparently.

Newest libgdx nightly along with the newest box2dlights nightly crashes with the following error:

Code: Select all

Hi!

I have the same issue.

As it s my first experience with box2dlights i was thinking that i made something wrong.

But it seems to be some modifications in the latest nightly.

Something is weird, source code seems to be correct.

Can someone please confirm if it's a nightly build issue, or did i made something wrong in my project ?

thx in advance

I also have this issue, was chugging along following a tutorial, then this hits I was so frustrated that I couldn't figure out how to fix it! Hopefully a fix will show up soon!

hi,

to avoid this issue, you need to build box2dlights from source.

cf this post : http://badlogicgames.com/forum/viewtopic.php?f=11&t=9707&p=43863&hilit=box2dlights#p43863

1: get box2dlights source from svn repository https://code.google.com/p/box2dlights/source/checkout

2: in box2dlights libs folder overwrite gdx.jar,... with files from libgdx nighty build

3: build box2dlights . there is a build.xml file, so you just need to launch ant

4: you get in a target folder a new box2dlights.jar and box2dlights-sources.jar files. Overwrite old ones in your project libs folder with the new ones.

5: your project should now be able to use box2dlights

it works for me

would you mind posting the .jar here?

Is there a proper way of resetting the lights? I have a bunch of pooled objects, changing the lights to new position makes them blink sometimes in old position when used with light.setEnabled(). Ive tried various orders of calling setPosition and enabling/disabling the light but i couldnt get it to work. Not disabling the lights works as expected, but marginally increased the cpu cost as they have to be culled.
