Problems with my code

[emacaode]

Hi all, I to have this problem where the board is not compiling. I saw this video on YouTube where they use a touchscreen TFT and they played flappy bird on it and I was trying to recreate it but it wont compile it says.Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Arduino Uno"

@emacaode, it looks like you did not copy the full code.

In the IDE, copy your code using edit -> copy for forum and next paste the copied code in a reply.

@emacaode, your topic was moved to a more suitable location on the forum.

@emacaode

myGLCD.print(“Score:”, 100, 80);

try
myGLCD.print((char*)"Score", 100,80);

[emacaode]

Thank you I will try that.

[emacaode]

It works for that line of code, but do I do it for all of them?

[emacaode]

I'm am a beginner I started about 3 months ago. What does that mean?

How are we supposed to know? You still haven't posted your complete code despite being asked.

BTW most of what you posted were only warnings NOT errors. Warnings can usually be ignored.

@slipstick

Warnings can usually be ignored.

I do ignore them. But they annoy me, so I try to see what the warning is about and eliminate them one by one.

Occasionally, never mind precisely how often, a warning has saved me a great deal of time and pain.

There's a point when you can know enough to ignore certain warnings. Noobs and for some time post-noobs should

1. turn on all warnings in the compiler
2. use warnings as an opportunity to increase general knowledge and confidence

Just sayin'.
