How to make a top-down game like Alien Swarm?

Hi, I have been looking at making a game, but want to make something different. So, I decided to go with a top-dow shooter like Alien Swarm, but I have absolutely no idea how to make the aiming system :confused:.
I am also trying to create special effects for bullets and explosions, but I can’t figure out how to animate them properly (I’ve got all the alpha stuff on planes done… lol)

If anyone has any example .blends or python scripts, it would be great.

Thanks alot :slight_smile:

Ha, funny. : P
That Question was asked once before and the Answer was given and explained by SolarLune.
Just search for »Alien Swarm«!

However, his Way was very mathematical and silly me would say it sounded complicated – you might do the Job with some simple worldPosition Setting of a Target-Aiming-Crosshair-Object to the hitPosition of a MouseOverAny Sensor and some simple TrackTo by the Player, might work just as well.

Thanks. I had already found that thread, but it was quite old, and there were no example files.
