move image over and keep it there

[Bone]

alright, im learning LUA, so i wanna make it when you hti right ti moves character over and keeps him there. right now the code i wrote, it moves it but when i release right it moves it back to original position

pad = Controls.read()
x = 60
y = 40
	
       if pad:right() then
		x = x + 5
		y = y +5
	end

screen:blit(x, y, person)
screen.flip()

can someone help so he stays in spot after he is moved. thanks

Mm.. I don't know LUA, but from what I can tell your creating two variables (x and y) and assigning them values, then providing a "keypad listener" to look for a right press to change those variable values.

The problem being that the variables will change back once this if statement is over.

Should you not create the variables and leave them empty then create an "if else" type statement to control the image..

please note this code is not real and simply an idea to try and help

if pad:right() then
     x = 65
     y = 45
else
     x = 60
     y = 40
end

excuse me if I am utterly wrong , simply trying to give you idea's.

i don't know lua, but i think it's because you've assigned the variables inside of the function. every time you read the controls, the x and y are reset (because they are after the controls.read statement). put setting x and y as part of the loading function (does lua even work in functions?) instead of whenever the control pad is read.

[EDIT] i think the guy above me would also have the same problem you're having, because it's telling the PSP "if you're not holding the controller to the right, then reset the image," which is exactly what you don't want to do...

I was trying to get at what you where saying, but didnt think about it quite so much when writting my "fake" code ..

person=Image.load("img/picture.png")
pad = Controls.read()
x = 60
y = 40

while true do    
	 if pad:right() then
			 x = x + 5
			 y = y +5
	 end
	 screen:blit(x, y, person)
	 screen.flip()
end

That should work.

That should work.

btw, if your trying to move your character right, then you should only need to increase the x value and not both the x and the y.
