Platform Shooter and AI engine

Tutorial Description
After seeing countless people asking about this in the novice Q&A I decided I would make one. Probaly the most complete platform engine on the GMC. Also contains a fully working platform shooter engine.

This engine has been through many version and has really evolved over the past few years, and it has been years (started 2008). As a result of this evolution, old code artifacts from earlier versions are still in this game. So from time to time, you may come across some redundant objects or pieces of code. Also different styles of coding are present, mainly due to my own development.

I have recently update the engine again (15/09/2011) This adds many cool features, ragdoll and physics using the GMphysic's EXT which I have included in the new download. The GM physic's EXT is pretty limited, but it eliminates the need for DLL's, something I haven't learned to use yet.

I want to put the history of the engine in, so this is the earliest version I can find:
Download old Version 1
I actually prefer the way the AI works in this version, even though it's simpler, it feels more tidy. Also the melee attack was cool.

old Platform Shooter
This was a platform shooter engine I made. This engine was born when I decided to merge the 2 engines together.

The controls are:
WASD to move.
Left click to shoot.
Mouse wheel to cycle weapons.
Right mouse to throw grenades, hold down to build up more power.
Q adds a silencer to your gun (Dunno why this is in there, it does not affect gun stats).
Space goes in to a slow mo thing (I think I was playing Red Dead).
R restarts the game.

Features Include:

• 2 Different AI's
• A friendly and an enemy
• Patrol
• Has line of sight
• Metal gear style explanation mark !
• Dodge things
• Grenades
• Also has cool partical effects
• Has a platform shooter engine as well with lots of features
• Ragdolls!

Also contains a pretty solid platform engine witch supports slopes, and includes a variety of easy to customize weapons and effects.

If you see your name here, but don't know why, you probably inadvertently gave me some code.

Enjoy

no offence, but the AI wont aim at you unless your exactly even with him. But I think the moving on uneven ground is great! 5/10

[MapleGuru]

Simple, but works great. Good Job buddy 10/10

[Crispy]

Ok got rid of the shooting up thing. Instead he jumps over things.

[jabelar]

You dont need registered for it.

<{POST_SNAPBACK}>

You do need registered, because it uses image_angle.

[emporer_safor]

Very cool indeed! 10/10. No problems. I find that this is great for beginers (who have Pro)

[Crispy]

Yes, in bullets step event. if you take it out it may work for unregistered to.

[ravener]

This is a great AI example 10/10 if you are going to make a new version make it so the AI has a gun arm that points toward the player!!

[SunTzus]

This isn't that hard to program, but it was functional, 7/10

Btw: only function it uses that's registered is image_angle= direction, whichis easy to implement to unregistered...

Maybe you should make it a bit more intricate like it being able aim at you w/o jumping by aiming DIRECTLY at you, it's extremely simple but it will help it loadz

[Crispy]

added AI sight line, and things that block the sight line. fixed a few gliches.

[MJGamesInc]

hey man can you make this so he can aim up and shoot if your jumping high over him and up on a roof or somthing???? please great help but thats the onlhy prob. i have LOL

[joshuarobillos]

This sounds great but can you make one for non pro users?

[Ziphe]

How do i make it so it shoots diagonally, I already have sprites for it also i have it so the bullets shoot were im at but dont follow me

[Crispy]

Updated, see first post.

[blaketheawesomedude]

Please make an unreg version.

[Hyper Break]

can you make this .gm6 ?

[Fede-lasse]

This is all glitchy; the player character turns upside down sometimes, the movement is glitchy, changing sprites is glitchy and the torso sprite of the AI is totally weird.

Except for that, it's good, I guess.

[Hyper Break]

broken link (the new one)

[Crispy]

Fixed the broken Link, fixed some bugs, added smoother movement. Working on having multipul enemys in the same room and not to shoot each other (harder than it sounds)

[harddrive]

Hey guys!

If you want to add a sound for a weapon, what do you do?
And how do you make the sound play when the weapon fires?

What do i write in the script, etc.?

Please answer!
I'm quite a noob at GM so I need detailed instructions.
