SA:MP дублирование полосы renderDrawLine Lua

[Yankay]

У меня вопрос, как убрать дублирование полосы renderDrawLine, у меня снизу рисуется адекватно, но эта полоса дублируется сверху и следует за персонажем, я двигаюсь и она двигается

ты рисуешь 250 точек назад и 250 вперёд от ближайшей точки. то, что сзади, может вылезать сверху.
убирай nearest - 250

local startIndex = nearest
