Character Movement : Issue with building after changing Project Product name in Player settings

IndieGameHustle 10 months ago in Game Creator updated by Marti (Lead Developer) 9 months ago 30

Having a issue:  After I  change the unity project  ( product name )  in player settings, there is a issue with character movement. The Character Movement issue only appears after the build. Works perfect in the editor, not after building. Also I am not getting any console error messages. I think this is a bug.  

Marti (Lead Developer) 10 months ago

Yeah definitely. It was a nice addition. We're just temporally removing it to identify the problem. We don't normally do this, but since we haven't been able to reproduce this problem, we're stripping everything we believe might be the case and reimplement it later. But for now, this will allow us assess whether the problem is here or not.

By the way, I'm marking the issue as Fixed, because I've already stripped all the necessary code. Tomorrow there should be a new Game Creator update available with this fix. If you still experience problems, feel free to reopen the ticket here.


Calling on Local Variable values has no effect

itsthehawke 10 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 1

Hey there,

so I created a health stat variable on my characters and I want to work with this variable further by adding a 'hurt state' if the health falls below a certain value and then ultimately "kill" the character when the health is on 0.

So far I have been able to change this var by colliding the enemy with my bullets, but nothing changes when my values are reached.

In my case, I use a local variable enemy_health, that has a default value of 100.

I have set a condition that checks if the variable value is equal or less than 25, then the character should become "hurt".

Same goes for checking if the health is equal or less than 0, then the character should turn into a ragdoll.

None of these actions ever start when reaching my designated values. Am I missing something?

Marti (Lead Developer) 10 months ago

Seems like you are missing a Trigger. Actions are list of instructions that are sequentially executed. Conditions, allow to execute different Actions based on Conditions.

Both of these systems require a Trigger to be executed. A Condition alone don't listen for scene events. You'll probably want a Trigger set to "On Variable Change". This trigger will be executed every time a given Local Variable changes its value. You can then execute the Conditions you already made and change the State of the Player for the one called Hurt, or kill it if the variable value is below zero.

Hope this helps!

time scale

Alienmadness 10 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 1

the timescale seems to effect the audio component of the UI.

for example when i set the timescale to 0 to pause the game.  i can no longer hear the UI clicks.  This may have been with the recent 1.0.2 update or the inventory module (just purchased and installed it).

Integration/Support for Procedural Worlds WAPI - Weather API - Actions and Conditions

Duffer123 10 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 1

I would see this as within core GameCreator - as the resultant Actions would then be vv useful in the Modules as well - particularly the Behaviour Module, Quest Module, etc.  Basically Actions controlling the weather if the Weather Asset is also compatible (as most are) with WAPI.... ;)


First person camera direction incorrect

Leslie Markley 10 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 3
I'm having problems with the first person camera positioning.  If I teleport the player to a marker (and then move them to the same marker so they're facing the right direction) then the camera still faces the opposite direction.

Also when switching from a tween camera to a first person camera, the first person camera tracks to the right of where the marker is facing.  I've also tried using a separate first person camera and I'm having the same issue with it.

Marti (Lead Developer) 10 months ago

Okay, this was a bit more complex than expected. I changed how the Teleport works so you will now have an option to rotate the Character towards where the Marker points at. This change also affected other Game Creator scripts, so I just can't post them here, since there are some dependencies. You'll have to wait for the next update.

On the other hand, there's still another issue. When teleporting a Character, if the Character has the Face Direction property set to Camera Direction, even if the character copies the direction of the Marker when teleporting, the camera will still keep its rotation, making the character immediately rotate where the camera looks at.

There's a solution for this too, however, which is creating another FPS Camera Motor and switching to this one AFTER the Teleport. When changing to a FPS motor, it's first positioned behind the Player, which is exactly what you want.

Hope this is clear. I'm closing this topic, since the fix is already done and will be available with version 1.0.3. Feel free to keep posting, however, if something wasn't clear. Cheers!


Bone requirements to drag and drop a new model

Niukeh 10 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 3
Marti (Lead Developer) 10 months ago

Ah yes. The only requirement is that the Character has a skeleton. Although not required, it is best if the Rig type is set to Humanoid. You can do that by selecting your 3D model asset in the Project Panel and, under the Inspector, select the Rig tab and select the Humanoid option.

No need to worry about bone names and you can have as many extra bones as you want.

If your 3D model doesn't have a Rig, there's a quick and easy way to attach a bone structure. Go to Mixamo and select the Upload Model option. Drag and drop your character and follow the simple steps. You'll get the same 3D model you had with a complete skeleton, ready to be used in Unity and Game Creator.


AnyIdea what this is about?

Andi Rutz 11 months ago in Game Creator updated by Marti (Lead Developer) 10 months ago 1

I'm trying to make a prefab of an enemy that takes damage. For some reason, the copies of the prefab don lose points in a stat, just the first copy. after it reaches 0 I get this error when attacking the copy but this one doesn't loose points in a stat.

Looks like you created a Stat, used it in a Formula, but then deleted that Stat. For example, you might have initially set a Stat named "strength" but then removed it, although in a Formula you're using the stat:strength symbol. 

Review your Formulas and make sure there's no typos in the Stats nor Attributes. Bear in mind these are case sensitive.

Player crazy behaviour

Andi Rutz 11 months ago in Game Creator updated by Marti (Lead Developer) 11 months ago 1


I'm trying to have the player grab a weapon from his back to his hand. It was all working well until I tried to set up variables for the object to be able to assign any equipped item. When I try now to use trigger player falls through the ground and if I try to unequip it destroys the player. See video link for Ref. 

Marti (Lead Developer) 11 months ago

You're probably destroying the Player instead of the weapon. See how your Global Variable Equipped Item references the Player instead of the weapon. This can probably be the issue.

Make sure to use the Inventory's On Equip and On Unequip actions list. This should be able to replace all the Action you have in your scene.


Player controls AI's target

Crispy 11 months ago in Game Creator updated by Marti (Lead Developer) 11 months ago 1

I want to have a feature in my game where the Player auto-attacks, and the user can press a button to switch targets so that the Player will cycle through all nearby targets that are within a certain radius IN FRONT of the Player -- kind of like the Can See condition. I think I should use a List Variable with the Nearest with Tag Action and the lock-on Action in the coming Shooter Module, but I don't know what other Actions I can use to achieve this.

Marti (Lead Developer) 11 months ago

Excellent question. You're correct in using the Gather Action. Here's how I would do it:

Disclaimer: While preparing this example we noticed some missing features in version 1.0.1. This will be added in 1.0.2, which should be available tomorrow.

First of all, we need a Trigger to start cycling though the targets. We will be using a On Key Up Trigger with the Right Arrow key option. Now we need to call an Actions list that gathers game objects that should be targeted and cycles them each time this Action is executed.

We'll use the Gather Components By Distance action, which searches around a given radius all objects with a certain component. There are many ways to do this, but our approach would be creating an empty script used to identify which objects can be targeted. To do so, right click on the Project Panel and select Create -> C# Script and give it a name, like TargetableObject. Now drag and drop this script to some objects in your scene that you want to be able to target.

Back the Actions we're going to have the following:

  1. Gather Components by Distance: Fills a List Variables with a collection of targetable objects. In the Component field, type in "TargetableObject" and create a List Variable somewhere in order to fill it.
  2. Game Object Variable: Now that we have the list variable filled, we need to pick an object. This can be easily done using the Game Object variable and storing the selected game object from a list. To cycle between objects, make sure to use the Next option under the Select drop down. This is an iterator that cycles one step at a time through a list variables. You'll also need to create a Local Variable where to store the targeted object. In our case, we created one below the Actions and called it "target"

That's all! Every time you press the Right arrow you'll cycle through different objects that have the TargetableObject component.

You could also use the Trigger "On Variable Change" to detect when the "target" local variable changes and make the camera face whatever object is in "target".

Hope this helps. I'm attaching an image showcasing this.


How to animate objects

Crispy 11 months ago in Game Creator updated by Marti (Lead Developer) 11 months ago 2

I made an animation of an object moving, but it uses another animator controller. Is it possible to trigger the animation with an Action? Is there a better way to go about animating objects?

Crispy 11 months ago

Ok, I got it to work by adding a trigger parameter in the animator and calling it with the Animate action. Let me know if there's a better way.
