Ask a Question / ads appearing after 3 attempts at main game
« on: December 05, 2018, 02:52:12 pm »

I would love to have the code for this! Currently my ads appear after the 1st play of the game when the main game scene transitions to the game over screen. Then it never appears again!

I would like the ads to appear after 3 attempts of playing the main game. I've tried using an attribute that counts every time "retry" is pressed - I think it should work...but it doesn't!

Any help would be great


Ask a Question / making videos for App Store/ Twitter/ Youtube

I wondered what is the best of kit to record game play and to convert to GIFs or relevant file format to submit to any of the above?
A free bit of software would be good!

Ask a Question / Fire Bullet in direction of a rotating arrow
« on: November 23, 2018, 11:22:20 pm »

I've been working on a game that uses a rotating arrow that goes from 0 to 90. When the mouse is clicked it fires a bullet, using the firebullet behaviour in the direction of the rotating arrow. This works fine.

However, in trying to update an existing game, I have successfully made an arrow that rotates from 0 to 180. (see code below - in order for it go from 0 to 180 - my workaround was making it go from -90 to 90). I can't however, get the bullet to fire in the direction of the arrow once it passes 0 and heads towards -90. When I fire the bullet when arrow direction is negative, it fires it towards 0. However when arrow direction is a positive number it works fine.

Here is the code for rotating arrow and amended firebullet behaviour using an arrow direction attribute.

Any help would be greatly received


Ask a Question / Moving an object to back within same layer
« on: November 13, 2018, 03:50:35 am »

Apologies for messaging with what I know will turn out to be an easy fix

Making a game where a “bullet” is fired then 2 seconds later, reappears at the centre of the character that is firing this. However, when it is recreated it always appears on top. I’ve tried moving to back and even drawing objects within another layer but to no avail. Thanks in advance.

After some FIFA copyright issues (!), I have renamed World Cup Heroes to "Football Invaders 2018"

Made in Stencyl and out now on iOS only

Hope you enjoy


What can I do to release an app on Android store for android version 3 or above. I may be wrong (I usually am) but it looks like I can only create games for Android on version 7 or above. Seems a bit odd as when I create an Android game on stencyl (which works), play store then throws up an error, saying that it doesn’t accept this for version 3 or 4. Weird.

Here is the error
"You uploaded an APK with an invalid signature (learn more about signing). Error from apksigner: ERROR (Jar signer CERT.DSA): JAR signature META-INF/CERT.DSA uses digest algorithm SHA-256 and signature algorithm SHA-256 with DSA which is not supported on API Level(s) 19-20 for which this APK is being verified"

Hi again! What is the best bit of software that records you playing your game. I’m thinking of the videos of gameplay on YouTube, AppStore etc. Thanks. John

Ask a Question / converting a game from flash to mobile ready
« on: May 22, 2018, 12:30:03 pm »

I've created a game in flash with dimensions of 640 x 480. If I were to convert this to android/ios, do I need to go through the process of resizing every background or actor to be the correct size for mobile devices? I can see there is a scale mode option in the mobile section of settings. Would this scale everything for you? Thanks in advance for your advice. John

Ask a Question / repeating a soundtrack
« on: May 09, 2018, 02:49:52 am »
Hi all,

I'm sure this is a simple request but how do you get a soundtrack to carry on playing once it has finished? i have put it in a loop but it plays the soundtrack over and over again from the starting position and sounds horrible! Any help greatly received!

Hi, I’m looking to make a football game. When the player kicks the ball (on space key press) the ball will travel in the direction that an arrow is facing. I’m wishing to make the arrow rotate from 0 to 180 degrees then bounce back again repeated forever. Any help would be greatly appreciated
