Guten Tag
Nach einer gefühlten Ewigkeit und ein bisschen spicken bei google und co ist es mir nun endlich gelungen, ein Feld (20x20) mit kleinen Buttons darzustellen welche man anklicken kann und sie wieder verschwinden
Doch leider werden die Bilder jetzt nur noch am Rand gerendert… was mache ich falsch ?
Es muss an der System_var mit dem bool in main liegen.. kann den Fehler aber nicht finden
[cpp]

int i,j; //

int mouse_y;
SDL_Rect dstrect;
SDL_Rect rects[20][20];
//________________
SDL_Rect newSDL_Rect(int xs, int ys, int widths, int heights)
{
SDL_Rect rectangular;
rectangular.x = xs + 120;
rectangular.y = ys;
rectangular.w = 20 ;
rectangular.h = 20;
return rectangular;
}

Und so…verschwindet die ganze Zeile beim drauf drücken wird aber ganz komplett gerendert
