"Matrix was suspicious" assertion error when launching with ?ea #5

Closed samreid closed 6 years ago

samreid commented 9 years ago

I tried running the simulation with ?ea to enable assertions and it failed to start, reporting a "matrix was suspicious" assertion error.

samreid commented 9 years ago

It is generally advisable to run with ?ea frequently during development, though sometimes it will interfere with performance testing.

The transform matrix trying to be applied:

6.123233995736766e-17 -1 -Infinity
1 6.123233995736766e-17 0
0 0 1

Caused by DispenserNode's imageNode being an empty Node (empty bounds), and fails line 102 of DispenserNode.

No longer able to reproduce this assertion. Closing.
