I get the following error if I try to build the examples on VS2017 with 0.10...

c:\dev\of_v0.10.0_vs2017_release\addons\ofxliquidfun\src\ofxbox2dutils.h(3): fatal error C1083: Cannot open include file: 'Box2D.h': No such file or directory (compiling source file src\ofApp.cpp)

Can't see anything super obvious so will use Linux for now.

I am new to OpenFrameworks and LiquidFun and have a simple question.

If can set the size of all the particles in the system by calling
particles.particleSystem->SetRadius

but how would I do that for a single particle?

Cheers

Hi,

I've been playing around with ofxLiquidFun and, more a question than an issue per say, but I was wondering if it is possible to :

1 : create elastic particles groups
2 : link them together with box2d joint
3 : controls one of those group with keyboard inputs

So far, I got step 1 (obvisouly) but when it comes to linking them, I can't seem to get each particles systems' body. ofxBox2dBaseShape has a pointer to a b2body but it doesn't seem to be used anywhere.

And I have the same problems for step 3.

I know that I can probably find a solution by adding support for the box2dParticlesGroup in ofxLiquidFun, but I have a feeling that I can achieve my goal without that.

Anyways, let me know.

Cheers

The title says it. I saw I can set the lifetime but how can I destroy particles that are offscreen?

box2d has

bool ofxBox2dBaseShape::shouldRemoveOffScreen(ofPtr<ofxBox2dBaseShape> shape) {
    return !ofRectangle(0, 0, ofGetWidth(), ofGetHeight()).inside(shape.get()->getPosition());
}

How can I add this to liquidFun?
