Portal Mind Challenge: Blue surfaces are bouncy #947

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Play the Portal Mind Challenge (portal.lua)
2. Jump on one of the blue surfaces

What is the expected output? What do you see instead?
I expect to not bounce around. But I bounce around.

What version of the product are you using? On what operating system?
Hedgewars 0.9.21 on GNU/Linux.

Please provide any additional information below.
The bouncy behaviour breaks the mission a little bit, as this can be abused to 
move the enemy hedgehogs around. I know this is unintentional, since in earlier 
versions of Hedgewars, there was no bouncing at all and the hogs on the blue 
surfaces were supposed to be pushed away by other means (i.e. a mine).

The blue surfaces should *only* repel portals, but not be bouncy.

Editing the mask.png accordingly should do the trick, you are probably aware of 
the ugly workaround.

The workaround is simple enough.  Put a few non-bouncy pixels above the bouncy 
layer.  I believe we've documented this too.

This is a won't fix because we really don't have that many land flags to toss 
around without expanding the format.
The initial discussion when bounce/anti-portal was added was specifically 
centred around flags that would work well together.

Given the workaround exists and the limited need for it, I don't think there's 
any reason to go about burning a flag here.

So the portal challenge stays broken, then?

No, it should be fixed, but by masking off the surfaces.

Okay, will this mask work?:

I have playtested it for myselves, it works fine.
This image is also posterized and pngcrushed for you. :-)

The mask has been updated and the issue is now fixed.
