Talking about Serious Scramblers game, Game development and HTML5.

I played a bit with GDevelop during these days and I was able to learn something which I want to share with you.

The Serious Scramblers prototype I published in step 1 now is getting a big update with patrolling enemies which players can kill by jumping on their heads and disappearing platforms, and everything without writing a single line of code.

Let’s have a look at the prototype:

Focus on the canvas, then play with LEFT and RIGHT or A and D keys to move, SPACE, SHIFT or W to jump.

Do not fall down or disappear from the upper side, watch out for disappearing platforms, the grey ones, and avoid enemies, or kill them by landing on their head.

Being GDevelop a no code tool, there isn’t any source code to show, anyway this is how I build the game.

First, I added four scene variables:

maxYPos: here I store the lowest platform y position, useful to know where to place a newly recycled platform.

gameStarted: boolean variable to check if the game started.

enemyRatio: probability of an enemy to spawn on the platform (0 – 99)

disappearingRatio: probability of a platform to disappear when the player lands on it (0 – 99)

Platform object has two interal variables:

initialized: boolean variable to check if a platform has been initialized (correctly placed, with an enemy on it, and so on)

disappearing: boolean variable to check if the platform is a disappearing platform.

And patrolling enemies have three internal variables:

left: maximum left position reachable before the enemy starts to move to the right

right: maximum right position reachable before the enemy starts to move to the left

goingRight: boolean variable. Is the enemy moving to the right? If not, it’s moving to the left.

Finally, this is the Events sheet, I suggest you to click on it to open it on a new page.

I did not use code, but I needed to learn a bit how GDevelop works. Anyway it was fun. I am going to add real graphic assets during next step, meanwhile you can download the entire GDevelop project.
