Problem with meshes

Hi,

I'm trying to make something like a flag using a mesh and mapping it to points on objects with physics behavior. This c3p shows the problem:

• I have a horizontal base with 'ropes' attached to each end
• Each rope is comprised of three sprites attached to each other with revolute joints
• The flag is a mesh with some points mapped to various image points on the ropes
• The pink box can be used to move the ropes
• The green button switches between mapping the ropes' image points to either the meshes position or texture

When position is mapped, the mesh is distorted off the right of the screen somewhere

When texture is mapped, nothing happens.

What am I doing wrong?

Mesh point positions aren’t in layout coordinates, they are relative to the object’s quad. So 0,0 is the top left corner and 1,1 is the bottom right. You’ll have to convert it over. So say you want to use x,y as a position you’d need to do:

X=(x-self.x)/self.width

Y=(y-self.y)/self.height

Texture coordinates are similar.

Thanks but I'm still not getting it! I've tried your suggestion without much more success:
