Is it possible to set up two cameras to make a split screen in the game?

Yes, at least in Ultra, idk about Leadwerks. Made a simple example:

#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);

    auto sz = framebuffer->GetSize();

    //Create camera
    auto camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    camera->SetPosition(sz.x * 0.5f, sz.y * 0.5f, 0);
    camera->SetClearMode(CLEAR_DEPTH);

    auto leftSprite = CreateSprite(world, sz.x / 2, sz.y);
    auto rightSprite = CreateSprite(world, sz.x / 2, sz.y);
    rightSprite->SetPosition(sz.x / 2, 0);

    auto unlitShader = LoadShaderFamily("Shaders/Unlit.fam");
    auto leftMaterial = CreateMaterial();
    leftMaterial->SetShaderFamily(unlitShader);
    leftMaterial->SetTransparent(true);
    auto leftTextureBuffer = CreateTextureBuffer(sz.x / 2, sz.y);
    leftMaterial->SetTexture(leftTextureBuffer->GetColorAttachment());
    leftSprite->SetMaterial(leftMaterial);
    leftSprite->SetShadows(false);

    auto leftCamera = CreateCamera(world);
    leftCamera->SetFov(90);
    leftCamera->SetRenderTarget(leftTextureBuffer);
    leftCamera->SetMatrix(camera->matrix);

    auto rightMaterial = CreateMaterial();
    rightMaterial->SetShaderFamily(unlitShader);
    rightMaterial->SetTransparent(true);

    auto rightTextureBuffer = CreateTextureBuffer(sz.x / 2, sz.y);
    rightMaterial->SetTexture(rightTextureBuffer->GetColorAttachment());
    rightSprite->SetMaterial(rightMaterial);
    rightSprite->SetShadows(false);

    auto rightCamera = CreateCamera(world);
    rightCamera->SetFov(90);
    rightCamera->SetRenderTarget(rightTextureBuffer);

    //Create scenery
    //Create light
    auto light = CreateBoxLight(world);
    light->SetRange(-10, 10);
    light->SetRotation(15, 15, 0);
    light->SetColor(2);


    auto box = CreateBox(world);

    auto cone = CreateCone(world);
    cone->SetPosition(1.25, 0, 0);
    cone->SetColor(0, 0, 1);

    auto sphere = CreateSphere(world);
    sphere->SetPosition(-1.25, 0, 0);
    sphere->SetColor(1, 0, 0);

    leftCamera->SetPosition(0, 0, -3);
    rightCamera->SetPosition(1, 0, -5);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) {
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

hi, another way is using buffers..

create some buffers...

 

//in my case camCount is 5
if (camCount>1)
    for (int i = 0; i < camCount; i++) {
        buffs[i] = Buffer::Create(context->GetWidth() / camCount, context->GetHeight());
    }


main loop:

    world->Update();

    for (int i = 0; i < camCount; i++) {
        buffs[i]->Enable();
        .. do whatever you need with the buffer, draw for example, move camera etc.
        world->Render();
        buffs[i]->Disable();

    context->sync();

a viede with 3 buffers, me a kinect and the ilusion of "looking through a window" the center one.

 

 

Paren el mundo!, me quiero bajar.
