Hi, I'm trying to program the scrolling of a background (NDS) and it's working. The only problem is, when I continu to press on the left et we are at the limit, the background stop (ok) but the value of scrolling continu to decrease (not ok). I tryed put a condition if to bloc the value to zero but it didn't work. there is a part of the code CODEÂÂÂÂscrollx += (Pad.Held.Right - Pad.Held.Left); ÂÂÂÂscrolly += (Pad.Held.Down - Pad.Held.Up); ÂÂÂÂif(scrollx
How do you know that the values are decreasing? Are you using something to print the values for you? Anyway.. are you using unsigned variables? That can lead to overflow and keep your variables always positive..
I use u32 scrolly, scrollx Yes I have a debug function that print it. Code: ÂÂÂÂPA_InitText(0,2); ÂÂÂÂPA_OutputText(0,1,6,"Position: (x=%d;y=%d)",scrollx,scrolly); Between I use PAlib to code on DS
Here's your problem.. those are unsigned numbers.. they are only positives.. try using int instead of u32
I have an other problem I need help with a table of string CODE#include or? #include int main(int argc, char ** argv) { string city[10]={"Ville départ","Port1"}; or? std::string city[10]={"Ville départ","Port1"}; } I'm using Devkitpro whit PAlib (using the build.exe)
You can use CODE#include using namespace std; int main(int argc, char ** argv) { string city[10]={"Ville départ","Port1"}; } or CODE#include int main(int argc, char ** argv) { std::string city[10]={"Ville départ","Port1"}; } same result..
And while we're on discussion of PAlib, how would I go about assigning array values to sprites? like if I have something like arrayx[10] and araayy[7], and I have an actual grid with sprites on screen.
I don't understand your problem linki Wouldn't be easier to use arrayxy[10][7] instead of arrayx[10] and arrayy[7] ?
thank you, it's working now! but my next problem is coming. Is it possible to have 2 PA_InitText? (in different function) like Code: function1() {PA_InitText(0,2);} function2() {PA_InitText(1,2);} int main() { while(1) { function1(); function2(); } }
