Please help me add physics to a sprite animation

Getting Started Newbie Questions
#1

please help me I’m trying everything I can to fix my code. I just want to add physics to a character (which is named “knight”) and I do not know what I am doing wrong. I’d really appreciate if anyone contributed to my code or tell me what I am doing wrong so that I can fix it. I would like to make the character move in all directions and make it jump with the jump button.

Here is the code: https://github.com/KrisAsante/PhysicsAnimationFail

Hi.  I helped, but I think you could have solved this on your own.

(Don’t take name of file personally, I had to name it something and I couldn’t think of anything clever.) 

Contains original and modified code.  Compare with diff program to see changes.

There were a number of simple errors.  The console showed the line and a simple lookup here: https://docs.coronalabs.com/api/ would have gotten you rolling.
 
The big issues I saw:
[list]

  • Do not use . or … in Corona paths: " ./ assets/sprites/land.png" 

  • You tried to do this:

    local knight = graphics.newImageSheet( “assets/spritesheet/knightIdle.png”, sheetOptionsIdle ) knight.x = display.contentCenterX - 200 knight.y = display.contentCenterY

You should have done this:

local knight = display.newSprite( sheetIdleKnight, sequence\_data ) knight.x = display.contentCenterX - 200 knight.y = display.contentCenterY

  • You used a default body for the knight.  That won’t fit the graphic.

  • You tried to listen for a bunch of listeners that were not defined.

PS - Please use standard sizes/fonts for the main body of your posts.  It is more legible for us if you do.

Remember when you apply phisics to a display object its like draw geometry figure lines in the display object border, I think it’s the same rule for sprites the only difference it’s you apply phisics to a display object that looks like a .gif instead of an object without multiple frames.
