使用libgdx加快游戏速度 [英] Speed in game with libgdx

问题描述

我正在使用libgdx进行游戏.目前，每个角色都有一个速度，该速度实际上对应于更新角色之前游戏等待的渲染次数.例如，如果角色的速度为15，则将每15个渲染器更新一次.我意识到这不是必须要做的.

I'm making a game using libgdx. For now, every character has a speed, corresponding actually to the number of render the game wait before update the character. For example, if the character has a speed of 15, it will be updated every 15 renders. I'm conscious that this is not how it has to be done.

执行此操作的正确方法是什么?我真的想以％速度，例如，一个字符的速度为85％.

What is the proper way to do this? I really want to make a speed in %, for example a character will have a speed of 85%.

推荐答案

使用delta.

Gdx.graphics.getDeltaTime()方法返回自上一个渲染帧以来的秒数.通常，此值非常小，等于1/FPS.

Gdx.graphics.getDeltaTime() method return secods since last render frame. Usually this value is very small, and it equal 1 / FPS.

@Override
public void render() 
{
    // limit it with 1/60 sec
    float dt = Math.min(Gdx.graphics.getDeltaTime(), 1 / 60f); 
    // then move your characted according to dt
    player.pos = player.pos + player.speed * dt;
    // or, you could mute the speed like this:
    player.pos = player.pos + player.speed * dt * 0.85;
}
