Tool in Unity, permitting to snap a game object position and rotation along a surface, using a tag.
Made in Unity 2021.3.17 (but should work for higher version)
#Included -This README with instruction -Full unity project (can be opened directly with Unity Hub) -Unity package, containing an exemple scene,as well as the script.
#How it work: -Assign the script to any object that you want to move along a surface (can be a group of object) -In the script, precise the tag that you want to use as surface -Assign this tag to any surfaces you want to use. This surface need to have a collider -If you want the object to align with the normal of surface, check the box "Align Rotation to Surface" -Move it along! You have two gizmo, one at the base of the surface and the original of the object. -To increase the offset from surface, you can change it in inspector or use the white arrow. -Ctrl-Z to cancel any movement
#Possible bug: -If you delete a tag, it may induce a bug if it is still registered in the inspector of the script, creating a warning message in console. Recreate the tag or de-assign it in the inespector -If two surfaces with the used tag are close together, the script will quickly change between the two. Adapt the Max Distance Detection, or remove the tag from one. -Big movement on small surfaces may break the snap, and teleport the object pretty far. I recommend using it on bigger objects only. -No surface detecte: check if the surface you want to use is in range, with the correct tag and using a collider.
