Physics objects passing into each other

Solar2D General Questions/Discussion
#1

I have this physics object declarations:

  
puck = display.newRect( 5, 5, 10, 10)  
puck.strokeWidth = 2  
puck:setFillColor(0, 0, 0)  
puck:setStrokeColor(180, 180, 180)  
physics.addBody( puck, {density=0.8, friction=0.2, bounce=0.5} ) -- linearDamping = 0.3, angularDamping = 0.8, isBullet = true  
puck.linearDamping = 0.3  
puck.angularDamping = 0.8  
puck.isBullet = true -- force continuous collision detection, to stop really fast shots from passing through other balls  
  
top\_boundary = display.newLine(5,5, 475,5)  
left\_boundary = display.newLine(5,5, 5,315)  
bottom\_boundary = display.newLine(5,315, 475,315)  
right\_boundary = display.newLine(475,5, 475,315)  
  
bumperBody = { friction=0.5, bounce=0.5 }  
physics.addBody( top\_boundary, "static", bumperBody )  
physics.addBody( left\_boundary, "static", bumperBody )  
physics.addBody( bottom\_boundary, "static", bumperBody )  
physics.addBody( right\_boundary, "static", bumperBody )

after applying a strong force to the puck, sometime it pass right into the boundaries, why does this happens? What am I doing wrong?

After googling is setDrawMode to hybrid and I’m seeing that physics boxes are not following the complete shape of the boundaries to be more precise they are exactly half the line, I think I’ll have to manually create a shape, but why is that shouldn’t the addPhysics automatically follow the line since it’s a rectangle?

I fixed this myself, if anybody read this searching for the same problem, drawLine didn’t work as I expected, it’s better to use drawRect.

I’m sorry I didn’t see this sooner, I would have liked to be able to assist you.

That said, well done on solving the problem and sharing your solution with the community :slight_smile:
