Unreal脚本性能对比

常见虚幻脚本简单测试

case 1: UnLua DevelopmentEditor

code:

local MathLibrary = UE.UKismetMathLibrary
local BeginT = MathLibrary.Now()
local TestVec
for i = 1, 1024 * 1024 do
	TestVec = UE.TArray(UE.FVector)
	TestVec:Add(UE.FVector(0, 0, 0))
	TestVec:Add(UE.FVector(0, 0, 1))
	TestVec:Add(UE.FVector(0, 1, 0))
	TestVec:Add(UE.FVector(1, 0, 0))
	TestVec:Add(UE.FVector(1, 1, 0))
	TestVec:Add(UE.FVector(1, 0, 1))
	TestVec:Add(UE.FVector(0, 1, 1))
	TestVec:Add(UE.FVector(1, 1, 1))
	MathLibrary.PointsAreCoplanar(TestVec, 0.1)
end
