How to include in a project

Seika uses cmake to build. To include in your project, add the following to your CMakeLists.txt:

# Include old_seika framework as a dependency
include(FetchContent)

FetchContent_Declare(
        seika
        GIT_REPOSITORY https://github.com/Chukobyte/seika.git
        GIT_TAG v0.2.0
)

FetchContent_MakeAvailable(seika)

Make sure to link seika to the target with target_link_libraries.

target_link_libraries(${PROJECT_NAME} seika)

Example

A simple example of creating a window and querying for inputs.

#include <stdio.h>

#include <seika/seika.h>
#include <seika/input/input.h>

int main(int argv, char** args) {
    ska_window_initialize((SkaWindowProperties){
        .title = "Simple Window",
        .windowWidth = 800,
        .windowHeight = 600,
        .resolutionWidth = 800,
        .resolutionHeight = 600,
        .maintainAspectRatio = true,
    });
    ska_input_initialize();

    while (true) {
        // TODO: Need to update this
        ska_update();

        if (ska_input_is_key_just_pressed(SkaInputKey_KEYBOARD_ESCAPE, 0)) {
            break;
        }
        if (ska_input_is_key_just_pressed(SkaInputKey_KEYBOARD_SPACE, 0)) {
            printf("space just pressed\n");
        }
        if (ska_input_is_key_pressed(SkaInputKey_KEYBOARD_SPACE, 0)) {
            printf("space pressed\n");
        }
        if (ska_input_is_key_just_released(SkaInputKey_KEYBOARD_SPACE, 0)) {
            printf("space just released\n");
        }

        static SkaColor windowBackgroundColor = (SkaColor){ 0.2f, 0.2f, 0.2f, 1.0f };
        ska_window_render(&windowBackgroundColor);
    }

    ska_window_finalize();
    ska_input_finalize();

    return 0;
}
