I create a UPROPERTY which type is FRuntimeFloatCurve.
I have three problems now:
-
How to make FRuntimeFloatCurve unmodifiable? I try this way but it still can edit in ue4 editor.
protected: UPROPERTY(AssetRegistrySearchable, VisibleAnywhere, Category = "Curve") FRuntimeFloatCurve Curve;
-
How to let the keys(points) be hidden? These keys(points) are too obvious for my curve.
-
I add these keys by “AddKey” function and the curve is smooth.
h0 = FKeyHandle(); Curve.EditorCurveData.AddKey(x0, y0, true, h0); Curve.EditorCurveData.SetKeyTangentMode(h0, ERichCurveTangentMode::RCTM_User); Curve.EditorCurveData.SetKeyInterpMode(h0, ERichCurveInterpMode::RCIM_Cubic);
But after I use “UpdateOrAddKey” function to update these keys, it has bad tangents.
Curve.EditorCurveData.UpdateOrAddKey(x0, y0, true, 0.1);
Does anyone knows how to fix these three problems?
Thanks.
