Collision box visibility in play mode

Hello,

is there a way to turn on visibility for every collision volume in play mode? With checking “Show → Collision” they are visible in the editor, but are not displayed after I click on the play button.

I attached a collision box to my character’s sword and I would like to check if its movement follows the weapon during animations or not.

Thanks,

Elathan

Hey Elathan , in playmode open your console ( ~ ) then type show collision
after that you should see the collision in play mode :smiley:

If i type “show collision” to the console I can see the player’s collision capsule but not the collision box I attached to the sword. I placed an instance from the same class to the map. In the editor i can see its weapon’s collision box, but in the game with “show collision” it is invisible as well :frowning:

Still does not work but I found a workaround to check if the box works in animations: in the character blueprint/viewport window it is visible, and the character plays the idle animation, I just replaced my idle with the attack animation, so i could see how it behaves - and yes, it works as I hoped it would :slight_smile:

I would not say it is resolved. The collision box is still invisible, and it would be nice if somehow there would be a way to display it.

If I use the command the collision box is still invisible.
My solution: if i uncheck the “hide in game” checkbox (Rendering), it is displayed in the game. I just have to uncheck it when I am done with the debugging :slight_smile:

you can press F8 to enable some of engine’s functionality back while running the game in editor. Among other things, this allows you to see collision under show/collision category in the top-left corner of the viewport or by pressing Alt+C

Thankyou Creo. How did you find pxvis collision - I don’t get it appearing with the predictive text of the console. Is there a master list somewhere?
