I've gotten it to work, thanks guys, the main thing that helped me is that blitzmax uses pointers only. anyways here's the updated code(I also didnt define update):

C++

#include <string>

using namespace std;

extern "C" {
    class cParticle {
    public:
          float x;
          float y;
          
          void Update(void); 
    };
    
    void cParticle::Update() {
         x++;
         y++;
    }
    
    cParticle *cCreateParticle(void) {
         return new cParticle; // is this right?
    }
    
    void cDeleteParticle(cParticle *p) {
         delete p; // is this right?
    }
    
    void cUpdateParticle(cParticle *p){
         p->Update(); // what about this one?
    }
    float ParticleX(cParticle *p) {
          return p->x;
    }
    float ParticleY(cParticle *p) {
          return p->y;
    }
}

bmax:

SuperStrict

Import "main.cpp"


Extern "C"
	Function cCreateParticle:Byte Ptr()
	Function cUpdateParticle(p:Byte Ptr)
	Function cDeleteParticle(p:Byte Ptr)
	Function ParticleX:Float(p:Byte Ptr)
	Function ParticleY:Float(p:Byte Ptr)
End Extern

'What data type? 
Local part:Byte Ptr = cCreateParticle()

Print ParticleX(part)+" , "+ParticleY(part)

cUpdateParticle(part)

Print ParticleX(part)+" , "+ParticleY(part)

cDeleteParticle(part)


End
