The game is unfunctional

I have started, and got a sprite with a walking and jumping animation, and have solid ground, but whenever I try to test out the game. The ground goes below the screen and the sprite does a second of animation before dissappearing. The character has loop active. The ground does not. What do I do?

You should post a capx file so we can help you

How do I do that?

You export a capx file. Check the top menu, you'll have an option for exporting a single file.

all i see is export project

that is it

no export as a single file

can you give me the instructions step by step?

You really should read the manual, especially the entry on Saving.

Search for the "save as single file" option

If I understood correctly, i'm assuming you have the Physics Behavior enabled on your character and the ground. If your floor and character is falling then you need to turn "Immovable" on in the Physics -> "Behaviors" panel on the (Default) left side, for your ground only.

Hopefully that helps.

Edit: Forgot! You can use the Platformer Behavior for your character and just add the Solid Behavior to your ground, and you should be ok.
