[@jimkincaidz]

Awesome, thank you!
So happy with how this series is coming along 🙂

[@VelvaryGames]

That's great to hear, glad you like it ;)

Brilliant work. Thank you.

Another useful video as always.

[@VelvaryGames]

Thank you :)

Slight problem I found while testing:
If you right click to unselect while drawing a line or rectangle it will instantly draw when you make a new selection. This is easily fixed by adding "holdActive=false;" and "previewMap.ClearAllTiles();" to the SelectedObj setter.
Otherwise, great video!

10:55 the Line95 In my case it only work as "if (ctx.interaction is SlowTapInteraction)" was it a mistake or i messed up something?

[@Shronkey]

This really helped! Thanks! :D

How to deal with rectangles, pentagrams, solid circles, and hollow circles with only borders?

Great tutorial can we see your face on your next tutorial?

[@VelvaryGames]

Haha, maybe. It requires more preparation

I work as a software developer

@@VelvaryGames Wow, i work as a game developer. How you started developing games?

[@VelvaryGames]

@@ManjeetKumar-xk8jf Sorry for the late response. It's cool that you work as a game developer. I'm a software dev who enjoys playing games, so it just happened one day that I tried game development, but it's just a hobby for me.

Hi. Thanks for the video. It helped me navigate myself through the mechanism. However I had some issues and don't know if it is specific to my project but this helped me solve it.
instead of the one in the video use this:
_dragRectangleBounds.xMin = Mathf.Min(_currentGridPosition.x,_holdStartGridPosition.x);
_dragRectangleBounds.xMax = Mathf.Max(_currentGridPosition.x,_holdStartGridPosition.x);
_dragRectangleBounds.yMin = Mathf.Min(_currentGridPosition.y,_holdStartGridPosition.y);
_dragRectangleBounds.yMax = Mathf.Max(_currentGridPosition.y,_holdStartGridPosition.y);

[@VelvaryGames]

Oh this is definitely a great way to get those values. Thanks for pointing it out :)

Thank you so much for the tutorial. The IsPointerOverGameObject() now throws a warning that calling the event system in an event callback only gives information from last frame. I fixed with RaycastAll. Code below:
List raycastResult = new List();
PointerEventData pointer = new PointerEventData(EventSystem.current);
pointer.position = playerInput.Gameplay.MousePosition.ReadValue();
EventSystem.current.RaycastAll(pointer, raycastResult);
// Old UI check: !EventSystem.current.IsPointerOverGameObject())
if (SelectedObj != null && (raycastResult.Count == 0))
This is in BuildingCreator.csm, in OnMouseLeftClick().

If anyone else faces this and you want to maintain similar logic you would just need to set it as a field variable in the update method and reference that instead in your cose
private void Update()
{
isPosOverGameObject = EventSystem.current.IsPointerOverGameObject();
.....
}
