Simple Button Class

[Degensquared]

I have just learned how to use classes and objects, so I decided to use my new found knowledge to save myself some time in the future .

This simple button class allows you to create button objects quickly, and check if they are pressed with a few easy commands.

Command List

button -> initialize: initializes the position, color and toggle depression animation.

button -> newlabel: allows you to put text onto the button. (for now only one font, in one size, but that will change. )

button -> clicked: checks if the button was clicked this frame and returns if it was clicked last frame.

button -> draw: draws the button, the depression animation, and the label for each button


Enjoy!

wow, Button/GUI classes seem to be growing popular in subject.

Good work!

Thanks I'm planning on adding custom sizes and fonts for the labels

It looks useful to me but I don't understand how I can use it.

I'm thinking of creating 3 buttons for a game I'm making. When you click it it selects a map. How can I use this for that? Of course if I were to use it, I'd note it as borrowed code.

Well, if you look at the example program, it should be kind of clear, but if not here you go:

You would need to set up 3 variables, each a pointer to the button class.
and the variables to check if the buttons have been clicked

create the objects using the new command,

initialize each of them.

check if they were clicked and are now not clicked

draw the buttons.

code:

var button1,button2,button3 : ^button var lastclicked, clicked : boolean new button1 new button2 new button3 button1 -> initialize (x1,y1,x2,y2, do you want depression animation, color of the button) ... button3 ... button1 -> clicked (clicked, lastclicked) if lastclicked and not clicked then      do whatever end if ... button3 ... button1 -> draw ... button3 -> draw

Loop that (make sure you use offscreenonly and View.Update!)
and it should work

do note that if you made your programme so the user or programmer only had to call one line, it would make it easier.
for example:

code:

loop     drawButton (any inside parameters such as X, Y, colour, text, procedure to be executed when pressed)     View.Update     exit when hasch end loop

hmm... well I personally like to split my programs into, input, calculations, and output. so that's why I split the draw and clicked commands, but I do think I could have labels included in the initialization.
