Projectile not showing up on layer

[MrAeon1111]

This doesn’t really help me a lot. I don’t understand it. I can’t find any nodes with that name. Would it be possible to have a concrete explanation on how that works? Thank you.

I'm assuming the screenshot you provided is from a tutorial.

What this is doing is getting the rotation of an object, calculating the x and y values to use based on the rotation, and then applying a force using those values. Effectively, this applies a force on a spawned object (presumably a bullet, a physics object) in the direction of the object.

Normalized x direction is a Math Function behavior that is using Cosine.
Normalized y direction is a Math Function behavior that is using Sine.

However, I see that the names are mixed up in the screenshot. So Sine is used for the x and Cosine is used for the y.

The multiplier is self-explanatory - you can adjust the power that is applied on the force. Larger multiplier means stronger force. It looks like it's using a health bar to adjust the power.

Also, good news! This bug has been fixed. An object shooting a bullet will still be able to shoot bullets when switching layers. We've also added the ability to adjust the Z order of the bullets.

Did you publish a new version of the app?
How did you fix it? Is it something in the behaviour that is visible so we can change the Z axis? Or we have to use a behaviour on that behaviour?

[MrAeon1111]

It would be nice that the bullets could have a tag just like an object.
It’s very useful when you have a hit box inside a collision box.
So you have a collision box for general collision and in the centre you have the real hit box

[MrAeon1111]

Or, do you have any work around?

1. App hasn't been updated yet.
2. The Z order property is editable in the shoot behavior itself.
3. I'm guessing you mean to have bullets ignore collisions of some objects - not possible at the moment. Treating bullets like objects would bring a lot of performance overhead. It would be a lot better to use actual objects instead since you can define custom behavior logic for each bullet.

I cannot find the Z option in shoot…

[MrAeon1111]

And yes, it’s exactly what I meant about the bullet object… it would be nice to have a both system. even if it has performance issue… the performance issue we can judge by ourselves when we do something..
Otherwise, it’s much too limited

As I’m not an engineer in IT or mathematician.
I would need a tutorial on how to shoot with a precise angle.
Trying to become an engineer now, it will be too late for me.
I would need a tutorial for that.

When you just have to have a node that say shoot by an angle. making this by yourself with math formula, it’s mind blowing weird.
Do you know somebody or something that can show me a complete and clean explanation how to do this?
Thank you very much
