Explosion Area Define

creativeapps

I want to petrol tank for example patrol tank blast size is 150 width and 150 height and that time I want to define perticular area suppose car is park from 200 pixel. That time I want to blast car also with petrol tank. And suppose car park 300 away from petrol tank I donot want to blast car.
How to do that. Please explain. Its radius count or something else?

You can get the distance between objects with the magnitude function. Say you have two game level attributes that track the car's position (carX, carY) -- then in the tank actor, you can can find the distance between the car and the tank (self) with:

magnitude( game.carX - self.Position.X , game.carY - self.Position.Y )

thanks for your reply. Can you or anyone expalin me step by steps I understand but confused.

I'd make an X and Y real game attribute. When the tanker explodes do a change attribute for the X and Y; change attribute position.X to self.position.X and position.Y to self.position.Y. Then do true/false change attribute explosion to TRUE.

Game objects would have a self.magnitude real attribute
Rules on the game objects that would take damage would look like this;
When explosion = True:
Change attribute self.magnitude to;
magnitude( game.position.X - self.Position.X , game.position.Y - self.Position.Y )
Rule; if magnitude = < 150 change attribute self.life to - ??? (whatever you want here)
if magnitude is >150 AND < 250 change attribute self.life to - ??? (whatever you want here)
if magnitude is > 250 change attribute self.life to - ??? (whatever you want here)
Chagne attribute self.magnitude to 0 (Put this last so it changes back for future explosions).

Hope this makes sense.

ok thanks for that
