Update Scene on IndexChanged in Dropdown list
Hello, I'm creating a 3d visualization of different measures (defined by various equations) in Unity. The model which I'm coding is tetrahedron. I visualize points inside it using function OnDrawGizmos(), which I know is a part of Update() function of scene. The problem is that I don't know how to update Gizmos color when I'm choosing different option from a dropdown (dropdown contains options of various measures and based on that measures and their equations I should visualize gizmos in different colors giving them color scale). When I start the scene everything is fine, I see gizmos in blue color, which I defined at the Start() function, but don't know how to assign different colors to gizmos, when changing option from dropdown. Any help would be appreciated.
Create a public function on your script, for example OnDropdownChanged(int value). In this function set to a Color member variable (e.g. gizmosColor) the color you want, for example in a switch-case. Then in your OnDrawGizmos() call Gizmos.color = gizmosColor;. Finally, in the Editor link the OnValueChanged(int) event of the dropdown to this function.
Basically, the UI will call this function, you store the selected option's color, and set the color when you need it (this is needed because Gizmos.color is static, so other scripts might change Gizmos.color before this script's OnDrawGizmos() gets called).
Thank you very much, I did as you said and it worked :)
