The ant sprite changes WHEN it fires but not BEFORE it fires. The ant graphic change must occur a moment before the firing of the projectile if the ant is to telegraph its attack.
Logic should look something like this:
1. Ant standing sprite (wait 3 seconds, for example)
2. Ant charges sprite (wait 0.5 seconds)
3. Ant fires projectile and changes back to ant standing sprite. (Return to step 1 and repeat)
