Debug.DrawLine disappearing in Scene view

Questions & Answers
1

Hello guys,

im working on a procedural city generator for unity, i used the debug.drawline method to visualize my generated streetnetwork/land lots and so on. Now i came to the point where i want to place actual GameObjects to the scene, but even if i place a single GameObject to the scene, the drawline method wont draw anything anymore.

I know that the lines are supposed to show up in the scene view, thats exactly where i want them.
I know that the 4th argument is supposed to be the display duration, however even if i set this to 9999f, the lines still wont show up.
And i also tried to pause the scene already.

Is it because im not using the update() method? I tried to use it, but i dont know how to pass over the arguments from my Polygon Object (which stores the points which are used to draw the lines) to an MonoBehaviour Class Object.

Thanks in advance.

I suspect you need to click the “gizmos” button in the editor, to make the Debug Lines show up in your scene. (top right corner, just above scene).

I got it to work now, i had to push the “Play” button before starting the generator.
Debug.DrawLine seems to only work when the “Game” is running.
