Going From Unity to Cocos complete newb - need help

May 25, 2024, 3:10 pm

Hi I’ve had a quick scout and I can’t find anything quite what I’m looking for but if there are forum posts already like what I’m about to ask then I do apologize and please point me in that direction…

I am a hobbyist who would like to become an indie game dev someday, but with that said at the moment I have casually over the past few years followed many unity tutorials and got reasonably good with C#

After last years unity license fee shit show I’m looking at alternative engines and I’m curious to see if cocos is good for my specific needs.

My intention is to make F2P casual mobile games including Infinite Runners and hyper casual games. One thing I’m finding both confusing and discouraging is that there’s so many different versions of cocos with 2dx, creator a c# version and all sorts with very few tutorials online.

Can someone please point me in the right direction for the following.

  1. Is Cocos a good fit for what I’m looking for?

  2. Which cocos should I be using?

  3. Where should I start, please explain why there’s so few tutorials on youtube and if is it important to only follow newer tutorials or is this engine highly backwards compatible with older versions?

I’d love to hear the experience of any other former or current unity devs who use cocos.

With that said this is already getting quite long and thanks in advance for any responses.

Keyboard won't close with Editbox

Here’s my code:

    player3Name = ui::EditBox::create(editBoxSize, ui::Scale9Sprite::create("whitebox.png"));
    player3Name->setAnchorPoint(Vec2(0, 0));
    player3Name->setPosition(Vec2(int_initialplayer3NameX, int_initialplayer3NameY));
    player3Name->setFontColor(Color4B::BLACK);
    player3Name->setPlaceHolder("Jay");
    player3Name->setInputFlag(ui::EditBox::InputFlag::INITIAL_CAPS_WORD);
    player3Name->setPlaceholderFontColor(Color4B::BLACK);
    player3Name->setMaxLength(12);
    player3Name->setText(UserDefault::getInstance()->getStringForKey("player3name").c_str());
    player3Name->setDelegate(this);
    player3Name->setReturnType(ui::EditBox::KeyboardReturnType::DEFAULT);

The keyboard comes up and let's me edit my label just fine.  problem is, when I hit the return button, nothing happens.  I've tried changing DEFAULT to DONE and it still doesn't close it.  Any ideas?

Camera zoom not respecting mask

August 12, 2024, 7:10 am

Hello. I am working on a 2D game in cocos v2.3.4. I have just added a feature with a main camera to render my game elements and a secondary camera to render my UI so that the main camera can be zoomed without the UI moving. The problem is that now the final picture gets bigger in the game instead of staying within the defined size of the mask.

The heirarchy looks like this:

Canvas (mask)

Main Camera
UI Camera
Game Stuff

Everything else

I am zooming the camera by increasing the zoomRatio to 1.8.

I’ve read the relevant documentation and it seems like this should be working so I could use some help. Thanks

Cocos Creator is too comprehensive for the projects I am targeting. I want to make a simpler editor, I want to make an editor based on visual programming like Buildbox, but is it more logical to download and edit an open source version of Cocos Creator or write an editor from scratch using cocos2d-x engine? What should I start by researching.

Cocos2d-JS 3.17 - Google rejected my app

October 1, 2024, 2:18 am

Hi all!

Google Play has removed my app and disable my dev account. They said my app is malicious, malware. I don’t know why they marked my app as malware. It’s just a simple knife throwing game (like Knife Hit), totally offline. I don’t request any sensitive permissions in my app. I also upgraded Android SDK to latest version 34. I submitted and scanned my app with virustotal and they said it is safe. I made 2 appeal but they still keep their decision.

I think that Google has marked the js-engine as malicious, because their policy said they don’t allow dynamic code execution at runtime (Javascript, Lua is dynamic language). Is that right ? Should I use C++ version of Cocos2d instead of JS for building Play Store app ?

Below is email from Google

Hi Developers at Gamera Studio,

Thanks for contacting the Google Play team.

After reviewing your appeal, we have confirmed our initial decision and will not be able to reinstate your developer account.

Your Google Play Developer account has been terminated due to violations of the Deceptive Behavior policy. We expect app functionality to be reasonably clear to users, and we’ve determined your app includes hidden, dormant, or undocumented features.

Additionally, we’ve identified that your app, Knife Clash ( com.free.**), falls into one or both of the two categories below:

  1. Your app contains code that could put a user, a user’s data, or a device at risk, and/or
  2. Your app does not deliver on the promises made to the user.

Thank you in advance!

Maximum number of sprites?

I’m loading multiple spritesheets, and this year, I’m trying to load a lot more layers to support jersey numbers. However, I’m not seeing all the sprites loaded, and I I shifted the order to check if it was a problem in the images, but that’s not it. It seems that I’m hitting some sort of limit?

Is there a limit with the number of sprites or perhaps I’m hitting a memory limit?

I can’t figure a good solution for this without loading 22 sheets of jersey numbers to overlay the players. :frowning:

thanks!

Can't remove event listening

December 23, 2024, 6:27 am
$

Hi! I’m currently working on a simple project, and as part of it, I needed to register player input.
So I added event listener, so whenever player presses inside parent node, other stuff happens.

onLoad() {
    this.node.parent.on(cc.Node.EventType.TOUCH_START, function (event) {
        this.Pressed = true;
        console.log("Pressed");
    }, this);        
    this.node.parent.on(cc.Node.EventType.TOUCH_END, function (event) {
        this.Pressed = false;
        console.log("Lifted");
    }, this);
}

And then way dowm the code I tried removing those, but it doesn’t seem to work

...
 this.node.parent.off(cc.Node.EventType.TOUCH_START, function (event) {
     this.Pressed = true;
     console.log("Pressed");
 }, this);
 this.node.parent.off(cc.Node.EventType.TOUCH_END, function (event) {
     this.Pressed = false;
     console.log("Lifted");
 }, this);
...

Code certainly does reach those commands, as other methods there seem to work, but nor .off(), nor even .destroy() called on this.node don’t remove the listeners.
Really need help with that as there should be many objects with that script and I really don’t want to pile up event listeners.
Also, probably important, I use cocos 2.4.10 + TS and don’t intend to switch version of this project
