Why is collision not consistent between play in editor and launch?

Hi,

I am working on a simple top down shooter to get to grips with engine. I want to make a pickup just like arena shooter pickups. This one currently gives me speed because that is only thing I have at moment.

So I set up collisions in my player character and pickup as shown in these two screen grabs.

Set my blueprint like this: http://i.imgur.com/AZW8Hj4.png

This works exactly as I would expect in play in editor function but not when I launch or package game.

Why? What have I done wrong or missed?

Thanks,

Daniel.

Hey Daniel,

I set something up with same basic settings you have and it worked fine in a Launched game. What exactly does not work for you in a Launched or Packaged game?

pickup box collides with player box, meaning I can’t pick it up, and previously my bullets would block me if I moved into them.

Since then I have started a new version of project which developed same problem. I removed my custom object channels and it now works fine. I don’t know why that makes a difference.

I would prefer to use custom channels but at moment I’m not.

I was wondering if it might have something to do with your custom PlayerCharacter channel. My biggest question is how were you able to stop character from falling through world if it was set to ignore World Static channel actors? My suspicion is that your problems stem from using a custom channel for your character. If you switch that to Pawn and make whatever collision adjustments from there, do you find you have same issues?

I thought same thing, it is as if player character channel was colliding with everything no matter what.
I’ll fire up old project and see if setting it to pawn works, I think it will to be honest, since I said before using no custom channels works as expected.

Also, if you don’t mind, could you let me know what you set default to when you created channel, and what you set defaults to when you set collision presets? This would be for PlayerCharacter channel and presets you made. I want to see if there’s a bug underneath all this. Thanks!

Setting my type to pawn did fix it in old project, and it was fixed with new project when I removed my custom channels.

I had a look and default collision response was “block” I cant remember what I used in newer project.

Hey BadPixel,

I was never able to reproduce this issue, and I wanted to check in and see if you are still seeing this behavior after upgrading to 4.4. If so, please provide some images for your current setup and I’ll take another look. Thanks!

Hey ,

I have not upgraded to 4.4 yet because I am going to be starting university this weekend (13th sept), and my uni provide an Unreal Engine License. Because of this I did not renew but will use product key provided by university. I will definitely try to reproduce it when I get that license though. I have had no issue using only default collision channels with custom channels removed. At some point I will probably need more though.

I understand. Please keep my informed, and good luck at university!
