具有浮点值的LibGDX乘以Vector2 [英] LibGDX Multiply Vector2 with float value

问题描述

有没有一种方法可以将Vector2与浮点值相乘?我以前在XNA中这样做是通过将归一化的方向向量乘以速度浮点来计算运动.这几乎是我的代码使工作正常的最后一步，但是似乎没有一个接受float值的Vector2的乘法函数.我可以手动仔细地x和y，但是应该有一个我不知道的方法.

Is there a way to multiply a Vector2 with a float value? I used to do this in XNA to calculate movement by multiplying a normalized direction vector with a velocity float. This pretty much is the last step in my code to make things work but there does not seem a multiply function for a Vector2 that accepts a float value. I could just mulltiply x and y manually but there should be a method for this i don't know about.

推荐答案

来自所以我想它叫做比例".如果要乘以整个向量，则只需对x和y使用相同的值即可.

So I guess it's called "scale". If you want to multiply the entire vector, just use the same value for x and y.
