JAVA Quick Backdrop collision bug

[AndyH]

Great update (MMF, JAVA and HWA) - thanks Clickteam!

There's still a bug with collisions on quick background objects.

Example here.

Run in MMF and it works with no problems, run to the left up the slope.

Compile to a stand alone JAVA app (there's a JAR file in the zip) and launch the JAVA app (the JAR) directly ... then try to run up the slope and there are slices of invisible obstacles. You can jump over or on top of the invisible obstacles.

On a similar note:

A 16x16 standard backdrop object set to obstacle will not have correct collision detection. Setting it to "collide with box" will make it collide perfectly on the 16x16 edges, however.

Actually you are right - background objects have the problem. My objects are 40x40 and it writes an invalid collision map but if I make it 44x40 the problem goes away.

Hope that this can be fixed so I don't have to resize the problematic background objects.
