Draw Capsule Gizmo
I want to draw a wireframe capsule gizmo, kinda like this:
void OnDrawGizmosSelected() {
Gizmos.color = Color.green;
Gizmos.DrawWireSphere(transform.position, 5.0f);
}
Just a capsule. Not a sphere. Is there an easy way to do this?
Class Variables color Sets the color for the gizmos that will be drawn next. matrix Set the gizmo matrix used to draw all gizmos.
Class Functions DrawRay Draws a ray starting at from to from + direction. DrawLine Draws a line starting at from towards to. DrawWireSphere Draws a wireframe sphere with center and radius. DrawSphere Draws a solid sphere with center and radius. DrawWireCube Draw a wireframe box with center and size. DrawCube Draw a solid box with center and size. DrawIcon Draw an icon at world position in the scene view. DrawGUITexture Draw a texture in screen coordinates. Useful for GUI backgrounds.
these are the only things that gizmos allow for so no ther is no easy way of having a wire frame capsule
Created a static method if people need.
public static void DrawWireCapsule(Vector3 _pos, Quaternion _rot, float _radius, float _height, Color _color = default(Color))
{
if (_color != default(Color))
Handles.color = _color;
Matrix4x4 angleMatrix = Matrix4x4.TRS(_pos, _rot, Handles.matrix.lossyScale);
using (new Handles.DrawingScope(angleMatrix))
{
var pointOffset = (_height - (_radius * 2)) / 2;
//draw sideways
Handles.DrawWireArc(Vector3.up * pointOffset, Vector3.left, Vector3.back, -180, _radius);
Handles.DrawLine(new Vector3(0, pointOffset, -_radius), new Vector3(0, -pointOffset, -_radius));
Handles.DrawLine(new Vector3(0, pointOffset, _radius), new Vector3(0, -pointOffset, _radius));
Handles.DrawWireArc(Vector3.down * pointOffset, Vector3.left, Vector3.back, 180, _radius);
//draw frontways
Handles.DrawWireArc(Vector3.up * pointOffset, Vector3.back, Vector3.left, 180, _radius);
Handles.DrawLine(new Vector3(-_radius, pointOffset, 0), new Vector3(-_radius, -pointOffset, 0));
Handles.DrawLine(new Vector3(_radius, pointOffset, 0), new Vector3(_radius, -pointOffset, 0));
Handles.DrawWireArc(Vector3.down * pointOffset, Vector3.back, Vector3.left, -180, _radius);
//draw center
Handles.DrawWireDisc(Vector3.up * pointOffset, Vector3.up, _radius);
Handles.DrawWireDisc(Vector3.down * pointOffset, Vector3.up, _radius);
}
}
I might be alittle late, ok VERY late but I figured out a way to do this pretty easily and wanted everyone to have a solution to this: I used the Gizmos.DrawMesh function and assigned a capsuled shaped mesh (which unity has as a default 3D shape) to a variable of my script and then sent that variable as a parameter to the DrawMesh function and I could pretty easily mess with the size and radius of the capsule.
works great for me, hope it helps anyone.
a small a code example would help alot. I have no idea how to create a capsule mesh via code.
