It's a really minor thing, and I'm not even 100% sure it's correct.. but as I tried to reverse-engineer your code, this small detail really tripped me up. Does it make sense?

I read the code in "frame()" function and find that " attron(262176 | board[i][j] << 8)", I know what attron means, but I don't understand 262176, what's the meaning?

It's good if there's a CMakeLists.txt。I write one that works for me. In this case, you need to create build and src folder, and put the code that needs compilation in src：

cmake_minimum_required (VERSION 3.0)


project(terris_demo)


find_package(Curses REQUIRED)
include_directories(${CURSES_INCLUDE_DIR})

aux_source_directory(src terris_src)

add_executable(${PROJECT_NAME} ${terris_src})
target_link_libraries(${PROJECT_NAME} ${CURSES_LIBRARIES})
