how to design more brush types in your code? thanks for your any help

For an asset of this quality and ease-of-use, it's incredible that it's free! The code is well documented and simple, and it's very easy to pick up. I had an issue that I couldn't solve, and I got very quick support. Give it a try!

In my case (3D project) - Camera (For drawable) -- Position : 0,0,0 -- Clear Flags : Depth only -- Projection : Orthographic -- Clipping Planes : Near = 0 -- Size : { // (Code from : https://youtu.be/3xXlnSetHPM?t=351) public void SetCameraSize() { SpriteRenderer rink = GetComponent<SpriteRenderer>(); float screenRatio = (float) Screen.width / (float) Screen.height; float targetRatio = rink.bounds.size.x / rink.bounds.size.y; float size = rink.bounds.size.y / 2; if(screenRatio < targetRatio){ size *= targetRatio / screenRatio; } {CameraOfYourDrawable}.orthographicSize = size; } } - Drawable -- Position : 0,0,0 -- Box Collider 2D Size : Screen size You can fit the drawable to screen (Main Camera is Perspective and Camera for drawable is Orthographic)

Simple an easy, good free asset! Works only with orthographic camera and Collider2D. I was able to make it work in 3D : - remove the need of collider2D in Drawable.cs, and replace the collider2D with a box collider. - Change camera to perspective - In Update(), modify like this : void Update() { // Is the user holding down the left mouse button? bool mouse_held_down = Input.GetMouseButton(0); if (mouse_held_down && !no_drawing_on_current_drag) { // Check if the current mouse position overlaps our image Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out RaycastHit hit, 100.0f, Drawing_Layers.value)) { // We're over the texture we're drawing on! // Use whatever function the current brush is current_brush(hit.point); } [...] } Enjoy!

I can't seem to get mine to setup properly. I followed the Youtube step by step, but my draw always draw on the center pixel only. Only one pixel changes and nothing else works. Does anyone know how to fix this? Thanks --- Update --- Found out that you had to set the Camera to Orthographic. Would have been nice if this information was in the document.

If I increase the size of pencil, it's lagging while drawing. Is there any other way to improve it?

The Eraser is drawing a black line instead or erasing. To fix this open the DrawingSettings.cs script and change the set Eraser method to this public void SetEraser() { Color c = Color.white; c.a = Transparency; SetMarkerColour(c); Drawable.drawable.SetPenBrush(); }

Good Asset

This asset is really good for drawing, easy to use and has a really nice documentation

big big thanks for providing this very helpful asset in free.
