Fix GameMaker Package Errors & Incorrect Exports

by Luna Greco 49 views

Hey guys! Ever run into those pesky errors when trying to create local packages in GameMaker? It's a common head-scratcher, and I'm here to help you sort it out. Let’s dive deep into troubleshooting those GameMaker local package creation errors and those annoying incorrect exports.

Understanding the Issues

First off, let's talk about the two main problems we're tackling today, specifically on macOS. Imagine you're wrapping up the process of creating a local package, you hit "OK," and bam! An error pops up saying, "Error creating package." The output window then throws some shade, mentioning the failure might be because createdump or the application isn't properly signed. Frustrating, right?

But wait, there's more! After you dismiss that error, you might try clicking "OK" again, and surprisingly, it might just work the second time. However, this unveils another issue: the exported .yymps file—that's your package—contains objects that you didn't even select to be part of the package. These are items that were chilling outside the "Asset Package" column in the Create Local Package window. It's like inviting the whole neighborhood to a party when you only meant to invite a few close friends.

Why is this happening, and how do we fix it? These issues often stem from a mix of factors, such as signing issues, internal processes tripping up, or unexpected behavior in the GameMaker IDE. Understanding the root cause is the first step to getting things back on track.

Decoding the Error Message

Let's break down that error message: "Error creating package. Failure may be because createdump or the application is not properly signed." This message is a clue, not a dead end. The key part here is the mention of signing. In macOS, applications and their components need to be properly signed to ensure they're secure and haven't been tampered with. If createdump (a utility for creating crash dumps) or the GameMaker application itself isn't correctly signed, you might run into this error. This is often the main keyword that helps us understand what's going on and where to focus our efforts.

The Mystery of Incorrect Exports

Now, onto the second part of the puzzle: the incorrect exports. This is where things get a bit trickier. You carefully select which assets you want in your package, but somehow, GameMaker decides to include extra stuff. This could be due to a glitch in how GameMaker handles asset selection during the packaging process. Maybe there's a hiccup in the way the IDE tracks which assets are intended for the package. Whatever the exact reason, it's a real pain when your package includes more than it should. This issue can lead to larger file sizes, potential conflicts, or even exposing assets you didn't want to share. It's a bit like accidentally sending a text to the wrong person – awkward and potentially problematic.

Step-by-Step Reproduction of the Issue

To really nail down what's going on, let's walk through the steps to reproduce this issue. This is crucial for understanding the exact sequence of events that trigger the error and the incorrect exports. By recreating the problem, we can better isolate the cause and find a reliable solution.

  1. Launch GameMaker: Start by firing up your GameMaker IDE. Get ready to dive into the project where you're experiencing these issues.
  2. Open the Project: Next, open the specific project that's giving you trouble. This will be the playground where we recreate the error.
  3. Select Create Local Package: Head over to the menu and choose the "Create Local Package" option. This is where the magic (or the error) happens.
  4. Enter Package Details: Fill in the necessary details for your package. This includes things like the publisher name (e.g., "Prismatic Realms, Inc."), the display name (e.g., "PRVector"), the Package ID, whether to sign the package, and the version number (e.g., 1.0.0). Make sure you're consistent with these details each time you try to reproduce the issue.
  5. Select Assets: This is a critical step. On the right side of the screen, you'll see your project's assets. Here, you want to drag only the PRModules group to the Asset Package column. It's crucial that you do not drag the internal group over. We're trying to isolate the issue where unselected assets get included.
  6. Click OK (First Time): Now, with your assets selected, click the OK button. Brace yourself – this is where you should observe the error message popping up. It's that familiar "Error creating package" dialog. Take note of the exact message and any additional details in the output window.
  7. Dismiss and Click OK (Second Time): After you dismiss the error dialog, click the OK button again. This is where the unexpected happens – you might find that the error doesn't appear this time. It's a bit like the error had a change of heart.
  8. Examine the Exported File: Now, the moment of truth. Use a text editor to open and examine the resulting .yymps file. This file is essentially a package of your assets. Look closely at the contents. You should observe that the file includes objects from the internal group, even though you didn't select them. This confirms the issue of incorrect exports.

By following these steps, you can consistently reproduce the error and the incorrect exports, making it easier to test potential solutions. Each step is a piece of the puzzle, helping you understand what's going wrong behind the scenes.

Diagnosing the Root Cause

Alright, so we've reproduced the error and the weird export behavior. Now, let's put on our detective hats and figure out what's really going on. This is where we dive into the potential causes, looking under the hood to see what might be tripping up GameMaker.

The Signing Suspect

That error message about createdump or the application not being properly signed is a big clue. Signing is a security measure on macOS that ensures applications and their components haven't been tampered with. If something isn't signed correctly, macOS might throw a fit and prevent certain operations, like creating a package. So, one of our prime suspects is a signing issue. This could mean that GameMaker itself isn't signed correctly, or that createdump (which GameMaker uses for crash reporting) is the culprit. A telltale sign is if you've recently updated your macOS or GameMaker, as these updates can sometimes mess with signing configurations.

The Asset Selection Snafu

Now, let's talk about those incorrect exports. Why are assets from the internal group sneaking into our package when we didn't invite them? This points to a potential issue in how GameMaker is handling asset selection during the package creation process. It's like the software has a mind of its own, grabbing things we didn't ask for. There could be a bug in the IDE that's causing it to include assets that weren't explicitly selected. Or, perhaps there's some internal caching or indexing issue that's leading to this mix-up. It's a bit of a mystery, but by digging deeper, we can uncover the truth.

The Double-Click Dilemma

That weird behavior where the error pops up the first time you click "OK," but not the second time? That's a head-scratcher. It suggests that the first attempt might be triggering some kind of initialization or setup process that's failing. Maybe the signing check or some other validation step is getting tripped up initially. But then, on the second attempt, whatever was missing is now in place, and the process can proceed. This could be due to a race condition, where certain components aren't ready when the package creation process starts. Or, it might be related to how GameMaker handles temporary files or caches. Whatever the reason, it's a valuable clue that helps us narrow down the possibilities.

Solutions and Workarounds

Alright, we've dug deep into the problem, reproduced the error, and diagnosed the potential causes. Now, let's get to the good stuff: solutions! Here are some strategies and workarounds you can try to tackle those GameMaker local package creation errors and incorrect exports.

Ensuring Proper Signing

If our prime suspect is a signing issue, the first step is to make sure everything is properly signed. This can involve a few different approaches:

  • Resign GameMaker: Sometimes, simply resigning the GameMaker application can do the trick. This involves using the codesign command in the terminal. You'll need to have the necessary certificates and provisioning profiles set up. It's a bit technical, but there are plenty of guides online that can walk you through the process. Resigning essentially re-stamps GameMaker with the correct digital signature, ensuring macOS trusts it.
  • Check createdump: Since the error message mentions createdump, let's make sure it's also signed correctly. This utility is part of GameMaker's crash reporting system, and if it's not signed, it can cause problems. You might need to locate createdump within the GameMaker installation directory and resign it separately.
  • Verify macOS Security Settings: macOS has security settings that can sometimes interfere with application signing. Make sure your settings aren't overly restrictive and are allowing GameMaker and its components to run without issues. This might involve adjusting Gatekeeper settings or temporarily disabling certain security features for troubleshooting purposes.

Taming Incorrect Exports

Dealing with those incorrect exports is a bit like herding cats – you need to be strategic. Here are a few techniques to try:

  • Double-Check Asset Selection: This might seem obvious, but it's worth double-checking that you're only selecting the assets you intend to include in the package. Make sure you're not accidentally dragging entire groups or folders into the Asset Package column.
  • Create a Clean Project: Sometimes, the issue might be related to project corruption or some other internal quirk. Try creating a new, blank project and then importing only the assets you need for the package. This can help isolate whether the problem is specific to your current project or a more general issue.
  • Manual Package Creation: If all else fails, you can try manually creating the package. This involves exporting the necessary assets and then packaging them together yourself. It's a bit more work, but it gives you full control over what goes into the package.

The Double-Click Workaround

That weird double-click behavior – where the error pops up the first time but not the second – might have a simple workaround:

  • Try Clicking OK Twice: Yes, it sounds strange, but if you encounter the error, try dismissing it and then clicking "OK" again. As we've seen, this sometimes bypasses the issue. It's not a permanent fix, but it can get you past the immediate problem.
