Decentraland warns your scene UI will clash with its mobile controls — but won't say where they are
I put two buttons at the bottom of a Decentraland scene, the way the platform's own mobile guidance says to. On a real phone, one of them wrote a permanent row to my database every time somebody tried to jump. Decentraland's mobile documentation does warn you about this. It says scene UI "will clash with the system controls." What it does not do — anywhere I could find — is tell you where those…
Decentraland warned that UI elements may clash with mobile controls, but did not specify where those controls are located. The author of the story found that their scene UI buttons interfered with the mobile controls on a phone, preventing proper functionality. The mobile client drew its own controls, such as a movement joystick and jump button, over the scene UI.
This resulted in unintended actions like accidentally feeding or teaching the creature when the user intended to jump. The author discovered that percentages used for positioning were ineffective, as the system controls were laid out in device pixels and could vary between phones. The solution was to remove the UI strip altogether, leaving only world-space taps for interaction.
