I’ve not presented myself yet… but anyway, I’ve finished the Hoppy Days tutorial and here is my take on it:
https://whereismybit.com/hoppydaysantartica
Differences to Yann’s original version:
-
Different sound effects (generated using https://jfxr.frozenfractal.com/#). -
Used the alternative way to avoid the jump bug (after jumping a flag variable is used skip the is_on_floor() check for one "physics frame", so it doesn't reset the y motion set by the jump). -
Use a rather convoluted way to allow the player jump from the edge of a platform (as it is sloped, the player is not on the floor, but sliding; if less than 100ms have lapsed since last is_on_floor()==true and the motion.y is less than a threshold, you can still jump). -
The cloud motion is smooth -
The lightning motion has been made more erratic, as it is not a normal solid object. -
There is an incoming portal and an outgoing one. -
Hurt animation for the player. -
Some collected coins statistics on the "Victory".
The level is quite short, but I’m proud of its playability. Hope you like it!
