Unity line renderer circle
This script allows me to draw a line in a full circle using the line renderer. What I didn't manage to achieve yet us to tell the line renderer only to draw like half a circle or just 90 degrees etc. What happens when you change to ? I didn't read the rest of the code. But that has got to be as in " degrees in a full circle. Seems like that should do something.

Properties alignment Select whether the line will face the camera, or the orientation of the Transform Component.
The specified value is the proportion of the line width at each segment. GetPosition Get the position of a vertex in the line.
GetPositions Get the positions of all vertices in the line. SetPosition Set the position of a vertex in the line. SetPositions Set the positions of all vertices in the line.

A selectable extension to provide a "cooldown" capability, preventing the button from being usable until a specified amount of time has passed. Segmented Control. A segmented control, like those found on iOS. It's two or more buttons side by side, where only one of them is selectable at a time.
Use Unity's LineRenderer to draw a circle on a GameObject
A stepper control, like those found in iOS. It's basically two buttons side by side, and can step its numeric value up and down. Range Slider. An example of an enhanced mask component able to work with the image data.
Enables picking on image parts and not just the Rect Transform. Disables the objects outside of the scrollrect viewport. Useful for scrolls with lots of content. Configures automatically - works in both vertical and horizontal but not both at the same time - drag and drop - can be initialized by code.

I added a texture with a dot, but it just gets stretched for the length of the line, which is obviously not what I want. I'm using C btw, if some code is needed here. I still don't know, why it's not working with a single dot. Edit2: I had to recreate the dot texture with a single dot and it worked, so there was some issue on my side.
Everything works now fine. Apply a texture with a circle to a material, assign that material to a line renderer, and attach a script to it that will scale the texture relative to the magnitude of the line.

I have a tower in my tower defense game im making with an upgradable radius and i would like when the user clicks the tower to show the radius as a circle around the tower.
My original thought was to create a cylinder gameobject and place it flat below the tower but when enemies come torwards the tower they "trip" and start spiraling everywhere yep had a blonde moment. Then I took the collider off the cylinder but this caused some really wierd things to happen between the ground and the cylinder major graphical glitches.
The tower is stationary and never moves and the radius of the tower can be accessed through radius. Also the camera is also stationary below is a screenshot of the game view please disregard it saying "new text" those are set at runtime. The Line Renderer takes an array of two or more points in 3D space and draws a straight line between each one.
A single Line Renderer Component can thus be used to draw anything from a simple straight line, to a complex spiral. The line is always continuous; if you need to draw two or more completely separate lines, you should use multiple GameObjects, each with its own Line Renderer. Great little script for Unity that makes a LineRenderer component shape into a circle or ellipse, given the number of line segments along with x and y radius.
While the above answer may work, I think your end goal could be achieved much easier with a little math and a circle outline Sprite with transparency. An extra script on every object that needs only a visual representation of a radius IMO is a little overkill. Rts style unit selection in unity. Creating a circle around your terrain.

And it should colors the triangle touched. My problem is that my circle doesn't rotate when my camera is rotating around the main object. So when i'm facing it, the circle is perfectly where i need it to be but when i'm at a 90 degree angle, i just see a line a circle view from side. Actually, my camera is rotating around a gameobject wich is the center of the object that i need to see. I don't really remember how line renderers work, I've been using my own system to draw lines for too long.
But IIRC, there's a toggle to determine whether the line renderer uses local or world space. Your alternative involves some slightly more expensive and considerably more confusing math to build the circle with world-space points that respect the camera's orientation relative to the line renderer object.
Unless you have a great reason to do otherwise, the best approach to a problem is often the most convenient.

Does this look like an ellipse too? If that circle looks like an ellipse too then it's all due to the aspect ratio of your display being incorrect.
