I want to know if there is anyway you could have an image that works like a button. If you could give some sample code with to help explain I would appreciate it very much. I am a noob when it comes to agk so if there was some article you found that helped you out when you first start a would also appreciate.

AGK has built in button commands which automises most of the process.

Scroll down to "Universal - Button" and make special note of the SetVirtualButtomImageUp() and SetVirtualButtonImageDown() commands.

Or you could use the image as a sprite and check for a button press with the following:


GetPointerReleased() is one when, you guessed it, the mouse button, or screen touch is released.

GetSpriteHitTest() checks if the coordinates are within the bounds of a sprite.

I use this in my UI engine and it works very nicely.

The main advantage of the built in commands is that by pressing a "virtualButton" the pointer is disabled so you don't get a click registered when the user clicks on a button.

Using sprites is better when you want to define the shape of your button a little better. I tend to use my own pointer UDT so I can set the pointer state manually when one of my sprite buttons is pressed.

What do you mean exactly? What is advantage of having the pointer disabled? I cannot figure out an use case for that. Thanks in advance for the reply.

When the user clicks on a virtual button the command "getPointerPressed" returns zero.

The advantage is that if you don't want another action to happen that is caused by "getPointerState" or one of the other pointer commands (in your code) this won't happen using a virtual button.

I was happy to see that my suggestion about a rectangular virtual button (issue #348) was accepted (and with medium priority). It will be nice when that is implemented.

I like virtual buttons. But it would be nice to have more than 12.

Yes 12 is becoming a problem with my new Level Editor right now... I may be asking for an increase

Thank you! It would certainly help with my own level editor and some of my game functions.
