I've made some fixes fo AI and added heat damage when entity is too close to the sun.
For this I added triggers into Box2dSensorComponent:
And then in startSensorDetectsBody method which is called from 'Box2World > ContactListener > beginContact':
The same way for endTrigger in another method.
And user implementation of any trigger (in this case for sun damage):
Any entity gets damage each 0.5 seconds in area of sun body sensor.
