hey Guys,

got some problems with my Tower Defense project (Episode 19 and following), my upgrade and sell buttons doesnt work ingame, the onClick event never gets called.

If i put a new button on the overlaycanvas and add the onclick event, i can upgrade my turrets, so i would say something is between the other buttons and my mouse.

Like Brackey, who had problems with the “graphic raycaster” from the topcanvas.

 

I someone want to take a look: https://drive.google.com/open?id=1x2AvTxFrto2wM7_QYdO6b6G7nhdRloJF

Thanks for any help!

It could be that a panel is blocking your button from being pressed, if the order in the hierachy is not correctly setup. Check that the buttons are always beneath other overlaying UI elements or just set for all UI elements which can not be clicked anyway the “Raycast Target” bool to false in the inspector.

try to figure it out over the last hours….. compared my project to the finished one from github, in the hirachy i can find no difference.

Can i log in the console on which element i click? Than i would know which element is in the way.

EDIT: Tried a lot of ways to get unity to show me what iam clicking on, no luck till now.

You can implement this one, to check which one you clicked:

Unity IPointerClickHandler

Good.

Just don’t write here anymore. A ‘solved’ button does not exist.
