Component Collide Stops Working

[SpiderPig]

The cube randomly bounces about but the collide member is only set to true for the first collision.  After that it fails to work.

#include "UltraEngine.h"
#include "ComponentSystem.h"
using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1440, 900, displays[0]);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();

    auto camera = CreateCamera(world);
    camera->Move(0, 2, -3);
    camera->SetClearColor(1, 0, 0);

    auto light = CreateDirectionalLight(world);
    light->SetRotation(35, 35, 35);

    auto floor = CreateBox(world, 100.0f, 0.5f, 100.0f);

    auto default_font = LoadFont("Fonts\\arial.ttf");
    auto ui = CreateInterface(world, default_font, framebuffer->size);
    ui->SetRenderLayers(2);
    ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);

    auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    ui_camera->SetPosition((float)framebuffer->size.x * 0.5f, (float)framebuffer->size.y * 0.5f, 0);
    ui_camera->SetRenderLayers(2);
    ui_camera->SetClearMode(CLEAR_DEPTH);

    auto label = CreateLabel("", 10, 10, 500, 200, ui->root);

    auto box = CreateBox(world);
    box->SetMass(1.0f);

    auto actor = CreateActor(box);
    auto c = actor->AddComponent<CollisionCallback>();

    box->SetPosition(0.0f, 5.0f, 0.0f);

    auto last_time = Millisecs();
    while (window->KeyHit(KEY_ESCAPE) == false && window->Closed() == false)
    {
        auto time = Millisecs();

        while (PeekEvent()) {
            ui->ProcessEvent(WaitEvent());
        }


        WString text = "Position : " + String(c->collided ? "True" : "False");
        label->SetText(text);

        if (time > last_time + 2500) {
            c->collided = false;
            box->AddForce(0.0f, 300.0f, 0.0f);
            last_time = time;
        }
        
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Component:

#pragma once
#include "UltraEngine.h"
#include "../ComponentSystem.h"


class CollisionCallback : public Component {
private:
public:
    bool collided = false, is_updating = false;
    int collision_count = 0;

    virtual void Update() {
        is_updating = true;
    }

    virtual void Collide(shared_ptr<Actor> collidedactor, const Vec3& position, const Vec3& normal, const dFloat speed) {
        collided = true;
        collision_count++;
    }
};

I checked it here as well.  It's the actors collision method that is not being called.  Josh are you able to take a look at this soon? 🙃

#ifdef DOUBLE_FLOAT
void Actor::Collision(std::shared_ptr<Entity> collidedentity, const dVec3& position, const dVec3& normal, const dFloat speed, std::shared_ptr<Material> collidedmaterial)
#else
void Actor::Collision(std::shared_ptr<Entity> collidedentity, const Vec3& position, const Vec3& normal, const dFloat speed, std::shared_ptr<Material> collidedmaterial)
#endif
{
	ActorBase::Start();
	auto actorbase = collidedentity->actor.lock();
	std::shared_ptr<Actor> actor;
	if (actorbase) actor = actorbase->As<Actor>();
	if (actor == NULL) actor = CreateActor(collidedentity);
	if (this->m_cameracontrols) this->m_cameracontrols->Collide(actor,position,normal,speed);
	if (this->m_collisioncallback) this->m_collisioncallback->Collide(actor,position,normal,speed);
	if (this->m_mover) this->m_mover->Collide(actor,position,normal,speed);
}

There will be an update for 1.0.2 later this week with fixes and some new features for image processing.

Update will be available soon.
