Ray casting

Ohh, i see. I thought u r changing the whole code for which i was little bit worried. And abt "bulky", i think the program might be more confusing becaz of poor arrangement and improper variable naming. Hope u would be able to understand it properly

Found some faulty logic in your EnemyTank1 class. In the checkTouching method, you have: The last else-if will never execute its code.

Got it. Thanks!!! But can u recognise the reason why it acts wierd when crate is again added to world and the and the path between them is obstructed?

I'll let you know if and when I find something.

Omg -- look at from where ay and by get there values in the Ray class.

I m not sure, but i opened ray class and then i changed the last most line i.e. (Obstacle.class).size()<=2 to .size()==0 From this i observed that if u keep the bot in the left hand side of the screen then the bot will not move towards the crate even if the path is unobstructed and if u place the bot in right hand side its not working. It moves on, no matter what, even if the path is unobstructed or not, it keeps on moving towards the crate if its in right hand side of the screen To observe the above one....click on solo....let the 2 crate be removed from the world....now let the 3rd crate be added in the world....now when the 3rd crate is addded... place the bot at every corner and then observe it I think after changing this line may be the reason of getting such type of error

You only implemented Obstacle in your B class as far as tanks are concerned. So, that is probably something to look into.

Sry if i misunderstood. Is their something else to be written in B class? I thought thier is no need of writing. If i have to write, then what should i write?

Either no tank should be Obstacle or all should be. The ray will not count well when inconsistent.

Is it working on ur pc? I tried but yet now crate mechanism is not working properly

If u don't mind can i ask u something? U may become angry. The request is not necessary. It can also be done if u deny. I request u to allow me to aks u something...plz It may be easier to solve the problem but u may become annoyed which concerns me a bit

That which annoys me is that you have to ask about asking.

It was a warning so that u can settle down yourself before reading it I want u to download the latest version of "Dawn of tank" I have used ray class only in blue bot class and i will be only using it for crate mechanism which would be more easier to fix the problem Download it and open blue bot...scroll down and read the 1st most commentt
