Ultra Engine testing

This requires a keen eye - with a transparent shader there is a hint of transparency even with alpha set to 1. Very hard to see the edge of the cube in this shot but you will notice it more when the cube is spinning. There's a faint hint of the cube behind the green sphere.

On the topic of transparency, that reminds me that in this example, you can notice a ghosting effect if the alpha is set to 0.0f

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 0, -3);

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    //Create a box
    auto box = CreateBox(world);

    auto material = CreateMaterial();
    if (material)
    {
        material->SetColor(0.0f, 0.0f, 1.0f, 1.0f);
        material->SetTransparent(true);
        box->SetMaterial(material);
        material = NULL;
    }

    //Entity component system
    auto actor = CreateActor(box);
    auto component = actor->AddComponent<Mover>();
    component->rotation.y = 45;

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        // Adjust the alpha of the sprite.
        float alpha = box->GetColor().a;
        if (window->KeyDown(KEY_UP))
        {
            alpha = Clamp((alpha + 0.01f), 0.0f, 1.0f);
            box->SetColor(1.0f, 1.0f, 1.0f, alpha);
        }

        if (window->KeyDown(KEY_DOWN))
        {
            alpha = Clamp((alpha - 0.01f), 0.0f, 1.0f);
            box->SetColor(1.0f, 1.0f, 1.0f, alpha);

Creating a text sprite for the first time is slow and is slower the bigger the text size is. Unsure if this one is "just the way it is" or it can be made faster? Slower in debug mode of course but still noticeable in release.

When a new font size is used, every character in the font gets rasterized to an image. However, probably 99% of those characters are never used. It would make sense to only rasterize them as they are used, but it will make things a bit more complicated and require a lot of testing before it works perfectly. Maybe I can add this in a future update?

I don't think ListenEvent is always working either. I have a lot of widgets parented to each other and little to no events are being received in the callback.

It doesn't work recursively. You need to listen for each widget.

Update

Fixed pixmap not appearing in 3D GUI
Fixed MOUSEENTER events not occurring
Entity::GetValue<T> changed to GetField<T>, but you should not use this anyway
RENDERLAYER_N constants are removed. You can declare your own if you want to use these:

	enum RenderLayer
	{
		RENDERLAYER_NONE = 0,
		RENDERLAYER_0 = 1,
		RENDERLAYER_1 = 2,
		RENDERLAYER_2 = 4,
		RENDERLAYER_3 = 8,
		RENDERLAYER_4 = 16,
		RENDERLAYER_5 = 32,
		RENDERLAYER_6 = 64,
		RENDERLAYER_7 = 128,
		RENDERLAYER_ALL = 255
	};
	inline RenderLayer operator|(RenderLayer a, RenderLayer b)
	{
		return static_cast<RenderLayer>(static_cast<int>(a) | static_cast<int>(b));
	};

How should we get the screen position of an object on a texture? Should the result be scaled down to the size of the texture and then reposition based on the panel position? I am not sure how to achieve this.

Just use the correct camera and the correct render buffer, and everything works out:

auto screen_pos = cam3->Project(box->position, buffer);

klepto2 · January 2, 2023

Josh, after all these bug reports you have solved recently ,and I just want to say:

Thank you.

UltraEngine is coming along very nice, and it is much better than I ever have thought it will be. The speed is really incredible, and the API is nice and smooth (of course there is space for improvements, but this will always be the case). Just a small sample:

In one of my researches (I posted it earlier in this thread), I started rendering a scene with a large terrain and a pseudo water plane (all tessellated). To test a feature I wanted to implement, I needed some kind of cascade rendering of the scene from multiple viewports (in this case 3). So I rendered the complete scene with lights terrain etc. 4 times, 1 time for the main viewport and 3 times for the cascades to a viewport (512,512) with an attached pfx shader with around 10-12 subpasses. And long story short: the speed was nearly the same as if I would render just the normal viewport. Of course there is some impact, but the same scene in Leadwerks would make it slow down to maybe 5 fps, if not less. In UltraEngine this still runs at 60fps.

This is amazing !!!

Got it to work, Thankyou. Should the sprites follow the same position system as the GUI? I mean 0,0 at the top left?

When I run it I get to about 2300. Each update gets slower and slower. I don't have an explanation right now why new panels stop appearing though. The render stats say more instances are being drawn.
