# Objective
- Improve reproducibility of examples
## Solution
- Use seeded rng when needed
- Use fixed z-ordering when needed
## Testing
```sh
steps=5;
echo "cpu_draw\nparallel_query\nanimated_fox\ntransparency_2d" > test
cargo run -p example-showcase -- run --stop-frame 250 --screenshot-frame 100 --fixed-frame-time 0.05 --example-list test --in-ci;
mv screenshots base;
for prefix in `seq 0 $steps`;
do
echo step $prefix;
cargo run -p example-showcase -- run --stop-frame 250 --screenshot-frame 100 --fixed-frame-time 0.05 --example-list test;
mv screenshots $prefix-screenshots;
done;
mv base screenshots
for prefix in `seq 0 $steps`;
do
echo check $prefix
for file in screenshots/*/*;
do
echo $file;
diff $file $prefix-$file;
done;
done;
```
