Nullpointer error + no other way in my eyes.

radi

solved!

koogs

which line is highlighted when you get the error?

radi

line 208 and line 208 leads to a function at line 300-303

java.lang.NullPointerException at beroepsproduct.mouseClicked(beroepsproduct.java:243) at processing.core.PApplet.mouseClicked(PApplet.java:2821) at processing.core.PApplet.handleMouseEvent(PApplet.java:2701) at processing.core.PApplet.dequeueEvents(PApplet.java:2612) at processing.core.PApplet.handleDraw(PApplet.java:2423) at processing.awt.PSurfaceAWT$12.callDraw(PSurfaceAWT.java:1540) at processing.core.PSurfaceNone$AnimationThread.run(PSurfaceNone.java:316)

Sketch won't run without images -- when I add filler images, I can't reproduce the problem. What did you click just before the error happens? Please describe the bug.

koogs

Line 232 lets game go up to 33

Game settings is twice that, ie possibly 66

Line 208 accesses cards[gamesettings] but you only have 64 cards, line 16

Proving this is easy, one line of debug just before line 208.

To reproduce it click start, 14 setjes, 14 setjes. (or to anything higher than 12) Breaks at i = 24. myCards only gets populated with 24 cards the first time startup() is run, so there isn't anything in there to find past myCards[23] when it gets to that line. Adding a call to startup() at line 205 fixes the problem.

@koogs that's true but it doesn't get to 33 because game is always even based on how this is written. The line of debug told me it breaks at 24.

println(mycard[i]);
