Trigger response is... not doing anything? (SOLVED)

Questions
#1

So, um…
I have written some code for detecting collision (because I don’t want to use the other collision system, I have things planned for not using that), however, the triggers are not working…? I have code here if anyone wants to look at it:

if message_id == hash("trigger_response") then
		if message.other_group == hash("wall") then
			if message.enter then
				if message.own_group == hash("up") then
					wall_up = true
					print("wall_up")
				end
				if message.own_group == hash("left") then
					wall_left = true
					print("wall_left")
				end
				if message.own_group == hash("right") then
					wall_right = true
					print("wall_right")
				end
				if message.own_group == hash("down") then
					wall_down = true
					print("wall_down")
				end
			else
				if message.own_group == hash("up") then
					wall_up = false
					print("wall_up_leave")
				end
				if message.own_group == hash("left") then
					wall_left = false
					print("wall_left_leave")
				end
				if message.own_group == hash("right") then
					wall_right = false
					print("wall_right_leave")
				end
				if message.own_group == hash("down") then
					wall_down = false
					print("wall_down_leave")
				end
			end
		end
	end

Any help would be appreciated~

Did you start with print()s at the top level (under if message_id == hash("trigger_response") then) and work your way down?

Upload a minimal sample project where it is not working.

Make sure your masking groups are set correctly.

Hope you can fix this quickly. Setting up the groups and masks and types etc. is a little complicated at first but once you’ve got it right it will be great. your code looks good to me, although I am not an expert so my advice would be that you look into how the collision objects are set up.

That explains a lot. Thanks for the help~

Okay, nevermind after 8 days because I was working on other things, but

I set the masks, and there’s no trigger response?
I put print functions under the trigger response, and I’m getting nothing…?

Is the script attached to the correct game object?

I often start by adding

print(message_id)
pprint(message)

…to the on_message() function to see if there’s any messages getting to it at all and what’s in them.

Yes, the script is connected to the correct game object (the game object receives input in the form of a message and I tested your method), however, I’m still not receiving a trigger response.

I tried putting a print message in the on_message() function and within the trigger_response, it turns out that I’m not getting anything from the trigger_response.

Please upload a .zip of your project and I will have a look at it for you.

#10

…I think it’s a bit too big to put it here? Is 19.5 MB (in a zip) too much?
It won’t upload.

#11

Make sure to remove .git, .internal and build folders.

#12

Emm… I’m starting to think it’s a problem with my computer. I may have to send it over by email or something?

(Maybe send it by messages?)

#13

Share it with me (bjorn@defold.se).

#14

Will do~

Thanks, I got the project, but it won’t build:

One thing to consider if collisions aren’t working is that the collision objects must belong to the same collection/world. More info: https://defold.com/manuals/physics/#caveats-and-common-issues

That makes a lot more sense. Thank you~
