Enemy Ai and melee weapons?

[hippokittie]

Hello again, I hate bothering you guys with what seems to be bacis stuff. I need some help editing or writing my own code for ai and melee weapons. I have their animations all imported (both weapon and monsters) and have set up some basic scenes to test them. I took a look at the prefab monster code as well as the prefab fps weapon code. I thought simply changing the code with my own values and equipping them would work for now, but it doesn't. I dont even know where to begin. Is there a tutorial for a basic ai and melee weapon system? Lua or c++ would work for it. Any packages possibly for me to take a look at? I am sorry so very lost.

Well, it's a bit difficult for me to point you in the right direction because I don't know where exactly you are stuck.

 

However, Aggror makes great tutorials, and one of them deals with setting up a simple AI that you might find useful:

I terms of a melee system though, there are various ways to approach this, some more trivial than others. I would recommend just treating the melee weapon as a gun, and then just check the distance of the raycast (should already be in the FPSPlayer.lua code) and if it's less than a certain distance, register a hit.

I keep seeing new people posting here a request for code that does exactly "this" or "that" for them, when they are needing to learn and understand basic lua/LE commands and LE in general. It's a little of wanting to run before you can walk scenario. People need to realize that for all intents and purposes that LE3.2 is relatively "new" for everyone, and even for the people that it isn't new, they might not have actually written code that does exactly what you are wanting to do. I am sure at some point in the future there will be plenty of generic scripts that will cover a lot of what some people want to accomplish, but without knowing lua or LE commands you won't be able to change it to do exactly what you want.

 

The fpsplayer & fpsweapon scripts are a decent place to start for what you are trying to accomplish with weapons. The inherent fpsplayer prefab will load the autopistol prefab and the fpsweapon script will handle its animations. So start simple: first make a prefab from your weapon model and a fpsweapon-like script that will handle its animations. Then try assigning it to the weapons variable in the fpsplayer prefab that you have placed into a scene. If you did things right then you should at least see your weapons prefab when you run the scene.

 

After that, then if you still have problems then post questions on the forum. There are always people here willing to help. What always helps a person to get a faster response to their problem is if they actually provide some way for Josh or the community to actually be able to reproduce the issue. You posting your models and scripts are always useful. And most importantly, if you want a specific answer then ask a specific question.

the issues with the ai is, that when I put the script on my own custom models, it doesnt fire off any of the commands set up in its code(the animations, attacking, moving nothing). The same with the melee weapons. I edited the codes for the animations to match up to mine (like changing the sequence numbers). But nothing. Not to mention, when I have the coding on my weapon and it exists in a scene it drops my fps to 10 from 70. without the code it doesnt effect it.

I have been learning a bit of lua on my own, but the issues I am having here are from using the default scripts in the engine. I asked for a tutorial to understand what I am doing wrong, also asked to just be pointed in the right direction not for people to spell it out for me. I want to make it so everything in my project works, and once it all works setting up a basic tutorial for my things, or simply making a free package of them, with comments on what each code does so new people like me can understand it better and learn from it

That's the problem I am trying to point out. We have no idea what you are doing wrong. You gave no specifics, no model, and no script for us to reproduce the problem. The best most people can do is guess at what your problem could be.

 

I want to make it so everything in my project works, and once it all works setting up a basic tutorial for my things, or simply making a free package of them, with comments on what each code does so new people like me can understand it better and learn from it

That's admirable and hope you stick with it to get to that point.

For the first problem with the enemy AI (harpy character), you need to open it up in the LE model editor and perform Tools>Resize. I like the Fit option to set the character's max height.

 

As for the rest of the issues with the harpy character, what is needed looks vaguely similar to what i had already responded to in a PM with another new person having similar problems. So here is my explanation for his specific character problems:

Hope this helps.

And the weapon issues?

And the weapon issues?

 

wow... I know maybe some things can get lost in translation from what is written on a post as compared to the the person's intent, but that is coming off pretty damn needy and more than a little ungrateful to the effort being put forth for them. I am going to just make the assumption that is not the case.

 

In any case - your sword model has a couple issues:

1) the model you provided has no UV's associated with it so it looks strange when a material is applied in LE

2) the model is rotated in the wrong direction - pointy end out should be towards the +Z direction (not a big deal though as it can be rotated in its script)

3) the model is way too big - scale down using the LE Model Editor by clicking Tools-->Resize -- use the Scale percent option.

 

Since your animations are all in one sequence, I created a text file to separate them. In notepad, I created the individual animation names and frame counts:

idle, 0, 25

swing, 26, 47

I saved the text file and then with the gladiouse model opened up in the Model Editor, I clicked on File-->Load Animation to load that text file. Then I deleted the multi-animation sequence and saved the model.

 

Next gut the fpsweapon script and rename it as 'gladiouse.lua' since there is basically only one animation and no reason to track ammo/clips/etc...

Gladiouse.lua

 

Once done with the script, load the gladiouse model into the scene and attach its weapons script to it. Save that as a prefab then delete it from the scene.

 

To use it with the fpsplayer, load the fpsplayer prefab into the scene and attach the 'gladiouse' prefab to its weapon script variable. When you run your game with the standard fpsplayer script, you should see the sword model just slightly below the camera, to the right, and angled up. Clicking the left mouse button will make it perform the "swing" animation.

I am very grateful, I was simply asking if the issue was the same for the weapon as the harpy, and about it causing my frame rate drop. I understand how it may sound, and I do thank you for being patient with me. I do wounder why the uv's didn't transfer from blender though. It may have something to do with sculptris perhaps, will have to look into it. I do thank you, and WILL accredit you for your help with everything you have done. I may ask a few question here and there from time to time, but only after I have looked at it more thoroughly. Again I am very grateful for your help. There are not many places for me to look about lua in comparison to leadwerks, other than here. If I have any more question, I will ask. Thank you

[macklebee]

No need to accredit anything to anyone. A simple thanks is more than sufficient on this forum. And questions are encouraged, but this goes for everyone - a person needs to state what is their specific issue. A question about how to setup a particular model to use with the fpsweapons script is a lot more specific than asking how to do a melee system. And of course if a person can provide scripts/files/pictures to help show the problem so people can try to recreate it, then the better chance your post will be answered.

 

As for the harpy model - 18K+ polygons seems a little high for a model that doesn't appear to have much detail. If possible, maybe retopologize to help bring that down some. As I didn't actually set it up to run around in a scene, I cannot speak to what the frame rate is doing.

[hippokittie]

Alright thank you ^.^ me and the other modeler are going to be retoping our monsters, most of the poly count is from the rounding of the body and face. I figured out how to make the melee weapon do damage, and goofing around with a bit of coding to figure it out, even found a way to randomize (between diffrent numbers) the damage to fit the rpg feel. I wrote a script that seems to be working that I will include in the complete package to be applied to specific bones to increase damage delt to the monsters if they are hit there, needs some tweaking and bug fixing but it kinda works . Would you suggest staying with lua or going more into the c++? I do have the full version is why I ask.

[macklebee]

I only have the lua version myself and it appears to be able to handle what I need it for... other than missing commands not exposed to it just yet. But that will come eventually. Though if I had the option to use another language for the core of game mechanics, I probably would use that. But lua is great for quick and dirty testing and troubleshooting.

[hippokittie]

The only languages I have programmed well in was c#, unrealscript, and actionscript 2. I am told that c++ is like c#, not sure what to believe there as they also said unreal script was like visual basic. If I do stick with lua, would you be able to suggest a site to help understand it better?

[macklebee]

For lua, I use these two a lot for reference:

http://pgl.yoyo.org/luai/i/_

and

http://www.lua.org/manual/5.1/

 

and of course, this for LE commands: http://www.leadwerks.com/werkspace/page/documentation/_/index/

and specific entity script functions: http://www.leadwerks.com/werkspace/page/documentation/_/script-reference/

[hippokittie]

Alright cool, thank you again if I have any problems I will let you know! Once I get the "weak point" script tweaked and working better I will shoot it your way, never know when you might need it.

Just read this thread. Maybe we need a guide for new users. Something that outlines the best way to get assistance.

 

I'm new to Leadwerks myself and don't know what or how you more experienced coders would prefer the question be asked.

 

Something like -Search forums first. If coding problem include code. Include screenshots etc.

I think those are definitely good steps to be applied to any forum or situation where you have an issue and are asking for help. The more specific a person can be by providing information/files/scripts/pictures/etc to demonstrate the issue will increase their chances that the problem can be addressed. Searching the forum for answers and then using the guidelines for posting bug reports basically should be followed when asking for help: http://www.leadwerks.com/werkspace/topic/6125-guidelines-for-bug-reports/

 

And do not get me wrong, asking broad open questions like 'how would you implement a melee system or inventory system?' are valid questions, but typically those will be ignored or just replied to in generalities.
