Raylib 事件

事件

分类

键盘事件 和 鼠标事件
键盘事件函数:

bool IsKeyDown(int key); //确定按键按下
bool IsKeyReleased(int key);
bool IsKeyUp(int key);
int GetKeyPressed();

最简单的逻辑控制

思路:我们运用IsKeyDown(Key的状态) 判断键盘是否按下这个键，然后按照上下左右的键位对小球进行控制

#include <stdio.h>
#include <raylib.h>
#include <time.h>
#include <stdlib.h>
void test_database()
{Vector2 p;p.x = 11;p.y = 2;Vector3 o;o.x = 10;o.y = 11;o.z = 10;
}
int main()
{srand((unsigned int)time(NULL));int x = 10, y = 10;InitWindow(800, 600,"Alaso_shuang");while (!WindowShouldClose()){BeginDrawing();DrawCircle(x, y, 10, RED);ClearBackground(BLACK);EndDrawing();if (IsKeyDown(KEY_UP)) y -= 1;if (IsKeyDown(KEY_DOWN)) y += 1;if (IsKeyDown(KEY_LEFT)) x -= 1;if (IsKeyDown(KEY_RIGHT)) x += 1;}CloseWindow();return 0;
}

你会发现这个小球一下子就出去了，我们需要设置帧率才会正常运转，优化上述程序

#include <stdio.h>
#include <raylib.h>
#include <time.h>
#include <stdlib.h>
void test_database()
{Vector2 p;p.x = 11;p.y = 2;Vector3 o;o.x = 10;o.y = 11;o.z = 10;
}
int main()
{srand((unsigned int)time(NULL));int x = 10, y = 10;InitWindow(800, 600,"Alaso_shuang");//需要设置帧率，帧率越低，移动速度越慢SetTargetFPS(60);while (!WindowShouldClose()){BeginDrawing();DrawCircle(x, y, 10, RED);ClearBackground(BLACK);EndDrawing();if (IsKeyDown(KEY_UP)) y -= 1;if (IsKeyDown(KEY_DOWN)) y += 1;if (IsKeyDown(KEY_LEFT)) x -= 1;if (IsKeyDown(KEY_RIGHT)) x += 1;if (IsKeyDown(KEY_ESCAPE)) break;}CloseWindow();return 0;
}

鼠标事件函数:

bool IsMouseButtonPressed(int button);
bool IsMouseButtonDown(int button);
bool IsMouseButtonReleased(int button);
int GetMouse();         //获取鼠标坐标
int GetMouse(void);

最简单的逻辑控制

#include <stdio.h>
#include <raylib.h>
#include <time.h>
#include <stdlib.h>
void test_database()
{Vector2 p;p.x = 11;p.y = 2;Vector3 o;o.x = 10;o.y = 11;o.z = 10;
}
int main()
{srand((unsigned int)time(NULL));int x = 10, y = 10;InitWindow(800, 600,"Alaso_shuang");//需要设置帧率，帧率越低，移动速度越慢SetTargetFPS(60);while (!WindowShouldClose()){BeginDrawing();DrawCircle(x, y, 10, RED);EndDrawing();if (IsMouseButtonDown(MOUSE_BUTTON_LEFT)){DrawCircle(GetMouseX(),GetMouseY(), 10, GREEN);}if (IsMouseButtonDown(MOUSE_BUTTON_RIGHT)){DrawRectangle(GetMouseX()-5, GetMouseY()- 5, 20, 10, RED);}}CloseWindow();return 0;
}
