" ABS"问题：/重载功能 [英] "ABS" problem :/ overloaded functions

问题描述

对重载功能的暧昧调用。无法解决它，我不知道abs是如何工作的，只是试图修复一个代码并用它来为视频游戏作弊哈哈。

如果你能改写那条线，任何帮助都会受到赞赏我很欣赏它。



我尝试过：

ambigious call to overloaded function. Cant fix it and i dont know how abs's work, just trying to fix a code and use it to make a cheat for a video game haha.
Any help would be appreciated if you can rewrite that line for me i'd appreciate it alot.

What I have tried:

float GetWavRoll(Vector dir)
{
	Vector forward(1, -dir.x, dir.y);

	Vector up(0, -dir.x, abs(dir.y + (1 / dir.y) + (1 / dir.y)));

	if (dir.x > 0 && dir.y < 0)
		up.y = abs(up.y);
	else if (dir.x < 0 && dir.y < 0)
		up.y = -abs(up.y);

	Vector left = up.Cross(forward);

	float roll = deg(atan2f(left.z, (left.y * forward.x) - (left.x * forward.y)));
}

推荐答案

另见 abs，labs，llabs，_abs64 [ ^ ]。

abs 在使用浮点变量时需要一个整数参数（我猜）。使用 fabs [ ^ ]。



[update]

正如理查德正确评论的那样，C ++的 abs 的实现已经重载。

[/ update]

abs expects an integer parameter while you are using floating point variables (I guess). Use fabs[^] instead.

[update]
As Richard correctly remarked, there are overloaded implementation of abs for C++.
