Game and keys

[pmu5757]

Hello
I intend to make a little game, and I wonder what is the best way to move for example a starship with keyboard keys.

Thank you.

Use tha Sprite dll, wichcan detect colisions with other sprite objects, and wiht edges or specific coordinates....

Thank you,
Ok I'll use it.
And how do I know which key the player has pressed ?

See this post: D-Pad Navigation Sample (?)
Instead of "If specialKey = ..." you should use

Select SpeicalKey
 Case cUpKey
  ...
 Case cLeftKey
 ...
 Case cRightKey
 ...
 Case cDownKey
 ...
End Select

Ok, that's for the device...
And if I want to make such an application for the desktop ?
Thank you.

Them use the keyPress event and use/look for the ASCII key value....
For instance, chr13 is the enter key...
Google a bit and you will find a complete reference to the ASCII key map...

Thank you.

It should also work on the desktop.

Ok for the keypressed event and the ascii table.
But what object must I choose for the keypressed event ?
I tried with the whole form, but with a form, I only have the "special keys" of the device.

Thank you

The only two standart control in B4PPc that suport "keyPress Event" are the Button and the Textbox.
Other controls have similar events...

You can change the default event triggered by adding an event...

For instance you want the same code to de used in more than one event, but That would cause too much code lines...
so just add an extra event that will overRide the default event of the control:

AddEvent("Button1",KeyPress,"MySub")
AddEvent("TextBox1",KeyPress,"MySub")

This will cause that both keypress events will be "linking" to the same Sub...

Thank you Cableguy, but I still have a question : what are ascii codes for the arrows of the desktop keyboard ?

Thank you.
