So after learning from the absolutely helpful beginner tutorial, I attempted to make a "Feeding Frenzy (fish eat fish)"- like game. The player fish is supposed to grow after eating a few fishes, so in the events sheet, I made each fish equivalent to a score depending on their size, and once the player reaches a certain score, it is supposed to grow. I wanted the fish to grow after reaching a score of 150 in order to eat the medium sized fish, so I did this:
Condition: System -> Compare variable -> Score = 150
Action: PlayerFish -> Set size to (142.51, 80.2)
So I run the layout to see if it works. It worked, however the problem is it automatically faces the right side (which is its non-mirrored version) and it will permanently be facing the right side unless it ate another fish. I added the biggest fish it is supposed to eat, so I made another event in which if the score reaches 1000, the player fish will increase size again to eat the biggest fish. The problem this time is the fish now permanently faces right, and even if it ate a fish, it will still never face the left side.
Here's the .capx file of the game: (Note: the sprites and background are not mine. I just borrowed from Google images first to see if I will be able to do this kind of game)
