How to make an enemy shoot directly at the player?

I have more than one open source examples on my website of 360 degree shooting on my website. maybe one will help.

I put some turrets into the game I'm making, and I want it to fire directly at the player, but it only fires in 8 directions, so if you run at it from the wrong angle, it won't be able to hit you. How can I fix that?

Can you upload the file? Post a link to it here and I'll fix it and send it back and you can see how it's done in the event editor.

Marv,.I just checked out your 360 Movement and Shoot Example engine (page 8). You are a math wiz for sure. Nice job....!!

Oh crap. That's right you can't use the 360 example, as it is, in TGF. Really sorry about that.

Check out this example:
Character 360 Direction Example

It is on page 19. Maybe you can adapt that.

all you need to do is:

make a large active object, (red circle i use)

at start of frame make this object invisable.

then for an event do this.

if (player) collides with (large active object)
have (large active object) launch (bullet) in direction of player relative to x0, y0.

((then click in the corner it will say 1+1.))

You can also do :
Always
- Bullet look in direction of player

This will make a directional missile that will not miss the target.

Fudge Francois. Why didn't I think of that. I use this method using a boomarang on the return journey of it back to the player.

For proper 360 degree movement, you can set the angle of the bullet to:

atan2(Y("Bullet")-Y("Target"),X("Target")-X("Bullet"))

and with the angle set, you can set the X position to

X("Bullet")+5*cos(Angle("Bullet"))

where 5 is your speed in pixels per frame, likewise for the Y position

Y("Bullet")+5*sin(Angle("Bullet"))

In builds of MMF2 prior to 248, atan2 was not supported. I'm not sure if TGF2 has it at all, so for angle you would instead use:

2*aTan((sqr((X("Target")-X("Bullet")) pow 2+(Y("Bullet")-Y("Target")) pow 2)-(X("Target")-X("Bullet")))/(Y("Bullet")-Y("Target")))

Excellent Jacob, and thanks. So throw away the boomerang return way?

Marv

Yeah, it's not really needed if you want 360 degrees. Also, you can do the same by constantly setting the Angle to the formula above.

on the bottom of the directions on the sprite menu (Ya know, the square with the eight directions?) there is a little bar with a slider that goes left to right. The further right you pull it, the more directions you'll be able to have and make cleaner, more direct firing sequences. Just set it to look at the player, and it will fire automaticly.

Doesn't work. It still only allows 32 directions.

sorry old thread...

Is there a way to do 360 degree aiming with Clickteam Bouncing Ball movement?
