Was having trouble understanding and getting my building system from before to work, so I’ve started trying to write it a different way. No clue if it will end up working or not, but it’ll be a valuable learning experience.
In my raycast I want to check if the collider’s tag is equal to “something” (in this instance “Foundation_SnapPoint”) and if so, move the instantiated object to the position of the collider. Looking at the old scripts, I thought what I have might work, but it isn’t an I’m not sure how to go about it. Any help would be appreciated.
Edit: The Foundation_SnapPoint is a child of the foundation. Just thought to check the transform on the SnapPoint and noticed the position is 1, 0, 0, which makes sense as it is exactly one foundation over from the actual foundation. I could see that being a problem, however, the object isn’t moving it’s position to 1,0,0 worldspace or anything when the raycast hits the SnapPoint, so I’m still at a loss there. Sorry if this is confusing, kind of confusing myself. lol
