Hi guys
For an assignment at school, I'm coding the first level of Contra in c++.
I've coded a huge part of the level and elements atm, but I'm having trouble finding an algorithm for the AI.
This is the spirtesheet I use for the soldier. As you can see, it looks in 3 directions (left and right not included).
My question is now: How can you make the soldier aim at the hero?
Do you have to substract the Y-positions from each other and then divide that number by 3 and get the right direction out of that number?
It would be awesome if somebody could give me a working solution for this.
Underneath, you find some pictures of the real game, just to give you guys an idea of how it should be.
Thanks in advance!
2D - Make enemy aim at hero
Hi MattProductions!
I have some suggestion for you.
With position of hero and enemy, you can identify vector from enemy to hero (Dir vector). Depend on type of enemy, it aims to hero with appropriate angle. For example:
1. Enemy is cannon: it aims to Dir vector.
2. Enemy is soldier: it has 8 options to aim (N, E, W, S, NE, NW, SE, SW). The direction it aims to is the vector which distance from soldier to it is shortest.

The most bland and simplest way you can do this, is check the Y position of the player against that of the enemy, if the player is higher, aim up, between a marge in front of you, straight, lower, aim down. This is however rather primitive and does't help you with shooting itself, only setting the right frame.
If you also want to shoot at the exact direction, you must do some vector math.
