Oh! Much better!
Thank you George.

I can see, there is a contest.
Its theme is unbound?

You can send any open source project.

Thank you for the great AI tutorial !
Is there a limit on the number of nodes and for the enemies ?

You are welcome. The nodes are limited to 300 per level in the demo, but you can increase the limit by playing with the arrays at the top of the ai.c file. Everything is commented.

The number of enemies is limited to 50 per level, but you can increase that limit by changing an array at the top of the script as well.

Hey guys, just wanted to point out a few things the multiplayer tutorial should fix/update.

1. Client and server environments are not properly mirrored, particle occur twice. To confirm I counted the number of particles on both the server and the client. For the machine gun the server had 50 particles, where as the client had 100. This can also be confirmed by adding a sound to the explosion effect, you should hear the sound once on the server and twice on the client.

2. I have yet to find a way to add sound into the "game" in a reasonable way. Example, so far I have had sounds play twice on the client and once on the server, zero times on the server and once on the client, only on the client, and only on the server.

3. The "hit" locations are inconsistent, this can be observed by having a client shoot a wall. You will notice the "bullet" patterns are different, server side appears to ignore the "accuracy" factor.

All in all this is probably the best tutorial I have ever seen, in more ways than one. If I make any improvements I will be sure to share among the community

Thanks for the feedback and bug reports.
A new multiplayer template version that fixes those bugs and adds sound support has been uploaded: http://superku.de/MPTemplate3Patch1.zip

Perfect, thank you Felix. You actually addressed a few thing the exact same way I did lol. I will keep playing with things and and keep trying to break it. If I find any bugs or anything I will be sure to let everyone know.

Ok found another bug, when landing on a declining surface the jump reset doesn't activate. Example, on the first map go to the top of the tower area and face one of the declining ramps. Hold forward and jump, when you land you will keep moving forward however you will be unable to jump until the surface angle changes or or until you stop. I found that changing the "8" value to "10" resolves this issue however I am unsure how this change effects the rest of the system.

if(ent_collision.z > target.z+player_height_above_ground+1+8*time_step+48*!!(player_data[i].status&(1<<2)) || player_data[i].speed_z > 0)

CHANGE TO:

if(ent_collision.z > target.z+player_height_above_ground+1+10*time_step+48*!!(player_data[i].status&(1<<2)) || player_data[i].speed_z > 0)

Felt I should mention that

Oh yes, the gravity code is a little whacky. Your fix seems perfectly fine to me though.
