Funny. The first time my game entered the exception handling code on the left, it froze for at least half a second. But only for the first time. I wonder if MSVC uses some lazy memory allocation in its exception instrumentation, or what could cause it. 🤔 #gamedev #cpp

Git diff of a piece of code that activates hurt animation for damaged objects in the game. Some kinds of objects don't have hurt animation, so I used to just wrap the code with try-catch. This caused a very specific problem, so I replaced it with a guard statement.

TGUI is a great library for building GUIs, but it seems it isn't tailored for pixel-art stuff. That or I am dumb and can't make it use the same scaling across the board 🤔 #WipWednesday #gamedev #TGUI

Screenshot of an options menu with hand-drawn widgets. Checkboxes and sliders use different scaling that buttons, panels, and tabs, making the UI visually inconsistent.

It seems that Google caved in under user backlash and presented us with the "advanced flow" for installing apps on #Android from unverified developers (=developers who value their privacy and rather pay 100$ for something meaningful). The flow is still a […] [Original post on techhub.social]

How the advanced flow works for users
Enable developer mode in system settings: Activating this is simple. This prevents accidental triggers or "one-tap" bypasses often used in high-pressure scams.
Confirm you aren't being coached: There is a quick check to make sure that no one is talking you into turning off your security. While power users know how to vet apps, scammers often pressure victims into disabling protections.
Restart your phone and reauthenticate: This cuts off any remote access or active phone calls a scammer might be using to watch what you’re doing.
Come back after the protective waiting period and verify: There is a one-time, one-day wait and then you can confirm that this is really you who’s making this change with our biometric authentication (fingerprint or face unlock) or device PIN. Scammers rely on manufactured urgency, so this breaks their spell and gives you time to think.
Install apps: Once you confirm you understand the risks, you’re all set to install apps from unverified developers, with the option of enabling for 7 days or indefinitely. For safety, you’ll still see a warning that the app is from an unverified developer, but you can just tap “Install Anyway.”
