Hello -
As I wrote in my introductory post, I am going through the tutorials and porting one of my apps from another engine in to Corona.
The game scene has four buttons - left, right, thrust, fire. I have a doubt concerning building the buttons. I required the widget at the beginning lines of game.lua (multiple scenes). Further down the code, I try to create the buttons, but am getting a NilValue error when trying to build the second button. The code is as follows:
– Create buttons with widget
local btnLeft = widget.newButton(
{
width = 100,
height = 100,
defaultFile = “BtnLeft.png”,
onEvent = handlebtnLeftEvent
}
)
btnLeft.x = 100
btnLeft.y = 580
local btnRight= widget.NewButton(
{
width = 100,
height = 100,
defaultFile = “BtnRight.png”,
onEvent = handlebtnRightEvent
}
)
btnRight.x=160
btnRight.y=580
local btnThrust= widget.NewButton(
{
width = 100,
height = 100,
defaultFile = “BtnThrust.png”,
onEvent = handlebtnThrustEvent
}
)
btnRight.x=950
btnRight.y=580
local btnFire= widget.NewButton(
{
width = 100,
height = 100,
defaultFile = “BtnFire.png”,
onEvent = handlebtnFireEvent
}
)
btnRight.x=1080
btnRight.y=580
When doing so, I get a NilValue error at “local btnRight= widget.NewButton(” . I am beginning to wonder if I invoke widget.NewButton only once and list the different buttons below. I’ve tried to find an example which has several buttons (I need to detect if buttons are kept pressed (to rotate and thrust my ship), but haven’t found one et.
Can you tell by the code incuded what I am doing wrong?
Thanks, regards.
