Functions⚓︎

Add·Tear·Flags ()⚓︎

void AddTearFlags ( TearFlags Flags )⚓︎

Calculate·End·Point ()⚓︎

static Vector CalculateEndPoint ( Vector Start, Vector Dir, Vector PositionOffset, Entity Parent, float Margin )⚓︎

Clear·Tear·Flags ()⚓︎

void ClearTearFlags ( TearFlags Flags )⚓︎

Get·End·Point ()⚓︎

const Vector GetEndPoint ( )⚓︎

Get·Non·Optimized·Samples ()⚓︎

const VectorList GetNonOptimizedSamples ( )⚓︎

返回一个向量表（VectorList）用于表达激光的路径。通常会返回沿激光路径均匀分布的51个点，相对于GetSamples()只返回表示激光路径所需的最少点。

Example Usage

local samplePoints = laser:GetNonOptimizedSamples()

for i=0, #samplePoints-1 do
    local pos = samplePoints:Get(i)
    ...
end

Get·Render·Z ()⚓︎

int GetRenderZ ( )⚓︎

Get·Samples ()⚓︎

const VectorList GetSamples ( )⚓︎

返回一个向量表（VectorList）表示激光的路径。与 GetNonOptimizedSamples() 不同，此函数返回尽可能少的点，同时仍然正确表示激光的路径。

例如，对于完全直的激光，GetNonOptimizedSamples() 将始终返回 51 个点，但此函数仅返回 2 个。

Example Usage

local samplePoints = laser:GetSamples()

for i=0, #samplePoints-1 do
    local pos = samplePoints:Get(i)
    ...
end

Has·Tear·Flags ()⚓︎

boolean HasTearFlags ( TearFlags Flags )⚓︎

Is·Circle·Laser ()⚓︎

boolean IsCircleLaser ( )⚓︎

Note

此函数无法区分不同类型的圆形激光，但可以通过其子类型进行识别：

0 - 线性激光（典型的激光，具有起点和终点）
1 - 环形鲁多维科（用于鲁多维科科技协同的受控激光环）
2 - 环形投射物（科技X）
3 - 环形跟随父物体（虚空之喉）
4 - 无碰撞（无碰撞溅射，例如科技零）
