Hi!

I want to draw 2d figure on screen.
I drawed 2d line by Draw2DLine function, but others can’t draw.

I drawed 2d box by K2_DrawBox function, but it was filled color, i want to draw unfilled box.
and i can’t find function for circle.

Especially, It must be drawed on forefront!!

I’m not very good with math, but I solved it this way:

In the On Paint function inside the UMG, I used Draw Line function.

To make boxes or triangles, just change the number of divisions and rotation.

I hope it helped.

Hi! f3l1xLtda.

Thanks to your answer.

But I want to draw figure by user’s mouse action at runtime.

If you want to draw freehand, you can use the same OnPaint function to draw on the screen. I made this widget to draw on the screen and calculate whether it is a circle, does not have 100% accuracy, but it works.

Thanks to your help, f3l1xLtda.

I will try to draw figure by referencing your asset.

Bye.
