delta-studio's Issues

Making sense of dphysics::ParticleSystem::Update

Looking at the code you've got:

    int n = (rand() % (100)) < 100; // Get a random number centered on the mean
    
    for (int i = 0; i < n; i++) {
        Particle *newParticle = m_particles.NewGeneric<Particle, 16>();
        newParticle->m_age = 0.0f;
        newParticle->m_life = ((rand() % 100) / 100.0f) + 5.0f;
        newParticle->m_texture = m_texture;
        newParticle->m_damping = 0.98f;
        newParticle->m_scale = 0.0f;
        newParticle->m_expansionRate = (rand() % 100) / 100.0f;
        newParticle->SetParent(this);
        newParticle->m_velocity = ysMath::LoadVector(float((rand() % 200) - 100), float((rand() % 200) - 100), 0.0f);
        newParticle->m_position = ysMath::Constants::Zero;
        newParticle->m_density = ((rand() % 200 - 100) / 800.0f) + 0.2f;
    }

Not sure if this is intended but the < 100 turns the expression before into a bool, and since % 100 results in values 0-99 you'll have essentially:

int n = 1;
for (int i = 0; i < 1; i++) {

I don't picture that's what you were after, because you could easily have rewritten that as an if...or just:

        Particle *newParticle = m_particles.NewGeneric<Particle, 16>();
        newParticle->m_age = 0.0f;
        newParticle->m_life = ((rand() % 100) / 100.0f) + 5.0f;
        newParticle->m_texture = m_texture;
        newParticle->m_damping = 0.98f;
        newParticle->m_scale = 0.0f;
        newParticle->m_expansionRate = (rand() % 100) / 100.0f;
        newParticle->SetParent(this);
        newParticle->m_velocity = ysMath::LoadVector(float((rand() % 200) - 100), float((rand() % 200) - 100), 0.0f);
        newParticle->m_position = ysMath::Constants::Zero;
        newParticle->m_density = ((rand() % 200 - 100) / 800.0f) + 0.2f;

You also calculated:

float expected = m_rate * timeStep;

Which I'm guessing is roughly how many particles you wanted to spawn in the timeframe, and that you wanted to try to randomly spawn them at different time frames so each update wouldn't be a continuous stream of new particles?

Bezier animation interpolation

Error when run the code invoke dll file

I run your program but got a system error:

"The code execution cannot proceed because d3dx10d_43.dll was not found. Reinstalling the program may fix this problem"

How can I fix this problem ?
I hope you can make a video about downloading and configuring to run this program, please!!

Thank you for your work!

Sum Input Device

Some devices or setups have multiple mice or keyboards. This can be intentional or the default OEM setup. For example, laptops can have multiple mice and most users assume that all will are interchangeable. Since Delta supports individual mouse and keyboard components, this assumption is not necessarily true leading to some devices working and others not. A composite component that aggregates all user input into one keyboard or mouse would simplify development where only one of each is required.

Assertion Error

Hello, according to your build instructions, I should run project/delta-studio.sln, which does not exist. I ran a cmake . in the root, and it built a sln just fine. Upon running the demos/delta-basic-demo/Debug> delta-basic-demo.exe, I got an error from the Visual C++ runtime saying that on line 37 of yds_breakdown_timer.cpp Expression: channel != nullptr. Not exactly sure what this means but its stopping the program from running correctly.

LNK1107 - invalid or corrupt file

After getting the files for SDL2, SDL-Image, and the boost files, and getting the CMake project to create the project files, I attempted to build all the projects, and it errored out with LNK1107 - invalid or corrupt file: cannot read at 0x112AB. Is there a specific version I am needing?

EDIT: I should note the error points to the SDL_image.h header file, within the delta-core project, when attempting to build the delta-basic-demo project.

Error while invoking cmake

Tring to run the the project as diescribed brings some erros's

1. There is no : "project/delta-studio.sln"
2. Invoking simple cmake command gives error :
