~~~~~~~~ I HOPE YOU DON’T IGNORE ME ~~~~~~~~~

Next time (please?) make:
- 2 balls in 1 level
- better effect for falling down
- restart button
- skip level button (with max. 2x)
- previous level button
- Passwords (for skip level)
- keys to make doors open
- a maximum of lifes (or you lose)
- enemys
- cheats

!~~PLEASE MAKE MORE PARTS, BECAUSE THIS IS THE BEST YOU MAKED FOR ME~~!

You said that perhaps the player needs to return a bit to gain speed. But what if he needs to return for gaining speed to the tile that you only allow “once”?

The correct anti-cheat procedure for any racing game is:
1. Whenever player passes through Tile N, store the time of passing (Time[N])
2. Whenever he passes some later tile O, again store the time (Time[O]).
3. Lap is only counted as correct if Time[O]>Time[N].

Even if player backtracks and returns to tile N, he then has to go through O again –> this check works.

The last part of the code (lines 231 and 232), there are 2 cycles that “read” the arrays that determine the position of the tiles:

for (y=0; y<=4; y++) {
for (x=0; x0) {
depth = y*12+x;

if you want to have larger levels, you must modify the second part of both fors:

y<= 4 and x<=4. If you want levels with 10 tiles width and 10 tiles long, you should change these values to y<= 9 and x<= 9. But remember to set ALL your arrays with 10 numbers, otherwise youll get errors. If you want a specific level to be shorter, just fill the “empty” spaces with zeros.

So, your code should look like this:

for (y=0; y<=9; y++) {
for (x=0; x0) {
depth = y*12+x;

Wow this tutorial is great!!! Thanks a lot Emanuele for being so kind to share some of your knowledge with us!
