Guided Missile

eroming

I am working on my first side scrolling game an I can't get the bosses missile to accelerate and continue tracking the main ship.

Thanks in advance!

Hey,
Create 2 real attributes (global) called ShipX & ShipY

Go inside the ship:
Constrain attribute ShipX to self.position.X
Constrain attribute ShipY to self.position.Y

When you shoot the guided missile, instead of accelerate toward use the interpolate:
Interpolate self.position.X to ShipX
Interpolate self.position.Y to ShipY

If for some reason the interpolation does not work, use the Move To behavior. Move to ShipX & ShipY

I know this takes up more processor time but instead of interpolate you can use accelerate.
This makes the missiles swing over the target and when you 'dodge' which gives a realistic effect.

Good luck!

Well, if he uses accelerate, or even accelerate toward, once the missile is dodged it will not come flying back. It's really your choice depending on the effect you want

No offence but it will come flying back.

I have this in one of my prototypes.
I used an accelerate to (the shipX and shipY)
It will keep following it but with a delay so when you move your ship and it misses it will come back in a nice circle. Looks awesome.

Not a problem Ludwig, I have *101* fever so I'm not sure if I'm thinking properly

Thank you for correcting me
