TowerDefense ToolKit 4

Try holding 'Control' while dragging/positioning the transform in SceneView. It will move the transform at a fixed 'step'.

 

I created a new scene and am using everything as default. When I use "Free Form Mode" (TowerManager -> Inspector -> Free Form Mode checkbox) I cannot place any turrets. It pulses red "Invalid Pos", and when I try to place it I get "Invalid Build Point" as a game message.

Any recommendations?

 

Hey songtan, when using assigned paths, is there a way to have every single creep randomly choose which path they follow? Right now "groups" will randomly choose a path, but I'm wondering if there's a way to set it so that each individual creep will, without having to set them up as individual items in the editor. Thanks!!

 

OK. I actually may have got it.

SpawnGenerator.cs

Code (CSharp):

1. public static Path generatePath()
2. {
3.     List<Path> pathList = Path.GetAllStartingPath();
4.     List<float> pathOddsList = new List<float>();
5.     for (int i = 0; i < pathList.Count; i++) pathOddsList.Add(1);
6.  
7.     int randPath = ChooseOption(pathOddsList);
8.     pathOddsList[randPath] *= 0.25f;    //reduce the chance of the path being used again
9.     return pathList[randPath];
10. }

SpawnManager.cs

Code (CSharp):

1. for(int i=0; i<subWave.spawnCount; i++){
2.     subWave.path = SpawnGenerator.generatePath();
3. ...
4. }

Seems to work OK. You see any issues doing it this way? Maybe too intensive for each creep?

 

@levi-jh, "Free Form Mode" allow you to build in any location with no collider. So if you are using default scene, you can build anywhere as long as it's not on the build-platform (build-platform are colliders). Have you try to build outside the build-platform? You can refer to the implementation in the scene 'Demo_Linear_FreeForm'.

@nnoom1986, Your code is fine. The only problem is the reduce chance of repeating path is not really working. The reason is every time the function is called, a new oddsList is created. So modifying the current one will not change what the next function call is going to use. Honestly, I think the result should be randomised enough even without it.

 

Errors upon import into a blank 3d project:

 

These are not errors. Just warning for some code that I've disabled. You should be able to run the scenes just fine.

I'll clean this up in the next update. Sorry for the confusion.

 

Hello @songtan ) I have some problem with support tower, when some tower in the radius upgraded support tower stop apply an effect on this tower, I found commended lines in UnitTower 340-347 after uncommend it started working but I have interesting bug. If I upgrade tower once it works perfectly but next upgrade having same problem

What can I do with it?

Thanks in advance)

 

Sorry for the bug. I'm guessing you are upgrading to the next level instead to the next prefab?

You don't need line340-347. What you need to do instead is add NewTower(this); in UnitTower line218. Should be just before OnSupportTowerBuilt();. That fix it for me as far as I can tell.

 

Its not a problem, thank you for fast answer) I will try to do it)

 

Hello @songtan it's me again, problem with support tower totally solved thank you!

I have one question if it possible can you please help me to implement 1 feature? I'm not so good with coding, but I can something)

So is it possible and not so hard to change the color of damage numbers to red (for example) when tower deal crit damage?

Thank in advance)

 

I've sent you a package via pm. Check it out.

 

Thank you! Have a nice day!

 

Hello, developer, is there a more detailed description document for reference? There are so many parameters in it that sometimes I can't think of what it means directly.(although the video has been explained more, I still don't understand many detailed parameters, such as what is the specific function of shield?)
If you have any documents, please send me one, thank you

Email：498585442@qq.com

 

The pdf documentation that include with the package is pretty much it. Regarding the individual parameters though, most, if not all of them has tooltip that explain what they do. Just hover your mouse over them if you need more information.

About shield: it's an additional layer of HitPoint that regenerate when the creep has not taking damage for the specified duration. So you can configure the amount of shield, the regenerate rate and the time it takes to start regenerating.

Hope this helps.

 

Hello

Is there any way to invert the zoom?

 

Line263 in CameraControl.cs, just change currentZoom+zoomSpeed to currentZoom-zoomSpeed

 

can i have the change to? Crit is important to show.

Im strugling to change the Way entry and exit is shown to the Maze. I need a Way to show the user where the enemies Will Enter and exit Maze. As of right now they have to Quess it. How is it calculated in code?

 

I've sent you the package for coloured crit popup text .

I don't understand how you are having a problem with the maze entry and exit. There's the path indicator to show it. If you disable it, there's the editor gizmos. It's always the nearest node the to the connecting waypoint and it's fixed once you have the waypoint placed. So you should have no problem knowing where is it yourself and place some visual indicator.

 

Its because i dont use the path indicator.
I created a Unit that looks like a wisp that flys trow the maze. So all my users conplain that they dont know where the Unit Will Enter or exit.

i really need some Way to detect it

 

I'm not sure what to tell you. Having a maze with no path-indicator is probably not the best idea. Entry or exit point aside, how do the player even tell how the creep navigate through the maze?

Anyway, like I said, the entry and exit point are fixed. There's nothing stopping you from pre-determined that yourself (You can just quickly play the scene in editor and see where the creep enter and exit the maze) and put some sort of visual marker on it.

 

Yeah hehe, i know man.
Im gonna try that, made a quad now.

Can you explain to me how the code works in platform builder script?
I changed the shader to URP Unlit, but now its not taking the material and copying it?
The issue is that the shader particle is way to light and see trow.

Can you help me make it possible to use URP Unlit as shader for the grid?

 

mat.mainTextureScale=new Vector2(x, y);

Its like this code is setting the new scale, but the shader is not copied on the other node

 

I made it work, i forgot to repeat texture.
And thanks for script to show critical damage song
As always you are a god in this branch !

 

is there a easy way to disallow diagonal movement? Like not crossing over corners BUT only go strait up and down?

 

There's a AStar game-object in the scene which responsible for the pathfinding. Change the path-smoothing (P Smoothing) setting to None.

 

hey @songtan ran into an odd issue and i have tried to look up to see if someone else hit this issue but can't seem to find anything. i cannot seem to get the "next upgrade" piece to work. i have done a fresh install of the latest package on unity version 2020.3.14f1. I added the "Assets/TDTK/Prefabs/Towers/Tower_Turret_Cannon II.prefab" to the tower list and added that tower to the "next upgrade" on the base cannon tower. once i upgrade it once it shows the "next upgrade" but it remains greyed out.

i have tired marking it "hide in inspector" and not, tried enabling it on the tower manger and not, but all have same results. I also have tired locking it via perk and unlocking but still same effect. any help would be appreciated

P.s. LOVE the Toolkit man, everything i could have hoped for

 

It's a bug. I must have made the mistake when cleaning up. To fix this, you need to modify Line244 of UITowerSelect.cs to this (The exclamation mark is the difference here):

if(!TowerManager.CheckTowerCounterLimit(nextTower.GetTypeID(), nextTower.limitInScene)){​

Sorry about this.

 

Thank you! that fixed it for me. I apricate the quick response.

 

Absolutely love TDTK! Is there any ETA on the next update?

 

Hey @songtan
Is there a easy Way to make UnitCreep Play idle animation while Stunned? Its like they are still running when getting Stunned?


Thanks in advance

 

Hello

How do i make a enemy heal other enemies AOe??

 

The only way a creep can heal other creep is to use a support creep with a heal effect. Like a damage over time effect in reverse.

 

I bought this asset some time ago but never had time to work on it. I’m very excited that im finally using it and a have nothing wrong to say about it, in fact is perfect and very useful for my project but im really having trouble with two things. First the save system if any of you guys can share the script that would be awesome and second i need to save after wave cleared (i trying to make an endless game).

 

I don't think there's a universally applicable save system, or a save system where you can just copy and paste from other game. Save system are often very specific to the game. Not only you have technical stuff like the save format, save location, you also have the the functionality like what get save and when. I'm afraid this is something that you have to solve yourself.

 

Hi, is it possible to make a tower which will use more than 1 "grid square", for example, an ultra heavy cannon that uses "2x2 squares"?

 

I'm afraid that is not supported. You can only have towers that occupy one node.

 

You Can increase the size of the platform square. So it looks bigger.

then under platform GO and deaktivate all other Towers, except the specific Tower you made. Then make your Tower and place the platform where you want. Now that platforms Tower is bigger and better

 

If I wanted to enable/disable abilities from lets say a main menu which list would I have to access the abilities from? I see abilityList in the ability manager script but can't seem to add/remove abilities using this list nor see what abilities is stored in this list via debug when game starts. Am I going about this the wrong way?

 

I'm afraid you can't. The availability of the abilities are set on AbilityManager Inspector in the game scene. The settings are self contained in each scene.

If you want to set the availability of the ability in the main menu (or from other scene), you will have to modify the existing script. The way it works right now, the AbilityManager script loads the ability from the db (see Awake() in AbilityManager.cs) and add them to the active abilityList depends on the its setting from the Inspector. What you need to do is override that setting with the one you have from other scene.

 

Okay thank you. I am going to mess around see if I can figure this out. No clue where to start with overriding the settings. There seems to be so many ins and outs of TDTK lol. I have a list that contains ability names that the user chose and I am going to try to enable disable those abilities in tdtk based off of the ability names.

 

Hello @songtan

Is there any way to make the creep stop for x seconds AFTER it successfull attacked?
I want the creep to like stop and wait then after x seconds start moving again.

 

Well, you can either have the towers applies a stun effect on attck, or you can hardcode the creep to get a stun effect when they are attacked.

 

I think you miss understand?
I want the monster to STOP after it has attacked and go in idle mode for x seconds then move on.

 

I see. In that case you will have to do some custom coding. The easiest way would be to just start a coroutine each time the creep has done an attack. Have that coroutine stop the unit from moving and attack for however long you need before resuming.

 

songtan, I'm looking to do 2 things.

1) When my tower upgrades to the next prefab I'd like it to retain the target priority (nearest, closest to goal, etc.). I'm assuming that UnitTower script line 64 GetTargetGroup command pulls the default target group selected in the tower editor? Is there an easy way to have it retain the target group of the previous prefab that was selected prior to the upgrade instead of pulling from the one selected in the editor?

2) Is there a way to have any new towers created default to not being available in the tower manager unless the checkbox is ticked? Currently any new towers are available by default so if I add a new tower I then have to adjust each scene to not display the new tower. I'm assuming there is a bool variable in the tower editor script or perhaps the TowerManager script?

Any help or hints on these two items is very much appreciated.

 

Yes they can be done with some slight code changes. Unfortunately I'm away from office for the next few days. I'll let you know when I'm back on monday.

 

Can anybody tell me whether this pack can be used to make a 2D tower defense game?

 

Yes, you can just lock the camera and use 2D sprite for the units. That said, the game still works in 3D space. So depends on the camera angle you are using, in some instances you might need to do a little script modification to stop the unit from rotating.

 

How do you use a prefab (say a wooden crate) as the platform? If I attach a platform prefab to an existing prefab the position of the tower is not consistent. I want to click on the top of the wooden crate and the tower options will be available there.

Set up:

Results:

But if I lower the platform prefab closer to the wood prefab, the tower selection will not work.
