Enemy Attack at Certain Range to Player?

JoshKahane

Hi

I was wondering. How can I make it so that for example at a certain range of my choice the enemy does a certain action (attack is my plan) when it comes within range of my player. So say the enemy is at a distance so that he is seen on screen, how can I make it attack when this happens?

Thanks.

try using the magnatude function, that should work, it determins the range between two points. you can read about it in the Wiki.

Hmm ok cool I'll check it out, thanks Mulcahy.

Ok after taking a good look at it it seems I can't figure it out. Could someone take a look for me please? And even better than an explanation would be just a quick demo that shows number two actor moves to number one actor when in range. Thanks.

Also, any attributes I need to make (for example player x and y, (Im guessing, would I need them?)) won't I need to make them for every single enemy or just once? I want to have several enemies but all react to the distance individually.

Ok. What I have done, instead of using magnitude (not sure which is better for performance) but I have created an invisible actor larger than the player which is constrained to the players x and y position so it is always over him. Now when the enemy collides with this large actor around the player they move to them.

Now I just have to work out how to have him stop running and attack.
