在C++中,根据地形高度更新玩家高度通常涉及到以下几个基础概念:
以下是一个简单的C++示例代码,展示如何根据地形高度更新玩家高度:
#include <iostream>
#include <vector>
// 假设地形高度数据存储在一个二维数组中
std::vector<std::vector<float>> terrainHeightMap = {
{0.0f, 1.0f, 2.0f},
{1.0f, 2.0f, 1.0f},
{2.0f, 1.0f, 0.0f}
};
// 获取地形高度
float GetTerrainHeightAt(float x, float z) {
int gridX = static_cast<int>(x);
int gridZ = static_cast<int>(z);
// 简单的双线性插值
float xFraction = x - gridX;
float zFraction = z - gridZ;
float h00 = terrainHeightMap[gridX][gridZ];
float h10 = terrainHeightMap[gridX + 1][gridZ];
float h01 = terrainHeightMap[gridX][gridZ + 1];
float h11 = terrainHeightMap[gridX + 1][gridZ + 1];
float h0 = h00 * (1 - xFraction) + h10 * xFraction;
float h1 = h01 * (1 - xFraction) + h11 * xFraction;
return h0 * (1 - zFraction) + h1 * zFraction;
}
// 更新玩家高度
void UpdatePlayerHeight(float &playerX, float &playerY, float &playerZ) {
playerY = GetTerrainHeightAt(playerX, playerZ);
}
int main() {
float playerX = 1.5f;
float playerY = 0.0f;
float playerZ = 1.5f;
UpdatePlayerHeight(playerX, playerY, playerZ);
std::cout << "Updated Player Height: " << playerY << std::endl;
return 0;
}
