Grid building engine bug

[fishrod]

Hello I made a grid building engine where you can place stone or grass tiles almost everything fully works but there are 2 bugs.
First when you click the checkbox the other checkbox somehow doesn't get unchecked.
Second when you place a tile in the top of the screen or all the way to left you can overlap tiles (The array starts checking at 32*32)
Take a look at the .mfa it's easier to understand the grid bug just place a tile in the top of the screen and look at the the debug menu.

Re: The Radio Button -
You're using it wrong. Don't use two separate objects for the different options - use just one object, and list the two options on separate lines.

Re: The Array -
In the array properties, untick where it says "Base 1 Index". At the moment, anywhere under 32x32 pixels will be at grid coordinates 0,0 - which is out of bounds for the array, which currently starts at 1,1.

Also, rather than creating new grass / stone objects, it's much better to create them as background objects, using the active object's "Add to backdrop" action.

So i did some of these things i have 3 questions.
1. How can i see what radio button is clicked?
2. I couldn't find the option "Add to backdrop" in the active object so i did that option in the event editor
3. If the object is placed as a backdrop does it much less lag? Because when i place 2000 object the game starts to lag badly.

Please take a look at the edited example and thanks for your help!

1.) Compare two general values -> Radio button -> Value of set radio button
(not wishing to be rude, but there is a help option in the object properties, which explains basic usage and would answer a question like this)

2.) Yes, that's what I meant... (you should really also use "delete created backdrops at..." to destroy the existing backdrop before you add a new one).

3.) It could certainly help, but there are a lot of different factors which might be contributing to lag, so it's hard to say. Changing the display mode from "Standard" to "Direct3D 9" in the application properties, will probably make the biggest difference.

So i did as you told 1 just 1 bug when trying to delete a backdrop it doesnt work i tried to delete all backdrops at Xmouse and Ymouse
Xmouse/32 Ymouse/32 and as last tried Xmouse/32*32 Ymouse/32*32 I even tried to delete all the backdrop when i press e but nothing gets deleted. Here is the edited mfa file please find out why i can't delete backdrops Thanks for all the help.
