HTML5 Background speed layer_hspeed("Background", x) won't work in HTML5

[thetafferboy]

Hi all,

Run in into a frustrating issue near the end of game development. I've made one 'infinite runner' type game, so the background scrolling speed needs to keep in sync with obstacles and game objects.

This works fine, controlling the obstacle speeds and background speed with a variable. However, when I export to HTML5, I notice the

layer_hspeed("Background",global.runSpeed);

does nothing in HTML5. The background wil move, but always slower than the other objects in the game.

As a test, I used

layer_hspeed("Background",global.runSpeed+100);

and sure enough, on Desktop, the background whizzed by - but in HTML5, it stayed the same speed.

Am I doing something wrong, or is there a way around this?

Does it still move in html5 or just not at all?

You might want to try using layer get id to see if this speeds it up. Rather than using "Background"; get its id into a var and use that. Otherwise I'd say it's worth reporting as a bug.

Html5 is an efficiency gaining nightmare. What works fine on windows will completely clog up on html5, so you have to constantly find innovative solutions.

As a workaround, I made a runner a while back and had two sprites rotating across the screen; as one exits the view/room it resets back to start. It worked ok.

Hi Micahel,

Thanks for your reply. It does move at 'original' speed - and the objects accelerate properly to the speed they are meant to get. I was thinking about a similar solution, I might just go down the 2 sprites moving route as I need to get the project wrapped up. I'll see if I can file a bug report, too.
