Steps to reproduce:

1. Make a Sprite - Add behavior Plataform

2. Make a Sprite with a small height - Add behavior Solid

3. Run it

4. Sometimes plataform will fall through

Observed result:

Plataform sprite does not stop in solid. Even with some quite large height it will happens.

Expected result:

It should stop on it

Browsers affected:

Chrome: no

Firefox: yes

Internet Explorer: no

Operating system & service pack:

Windows 7 SP1 Intel i7

Construct 2 version:

r137 64bits

Seems to be connected with system load or dt to big causing large steps. Does not affect other browsers.

I can't reproduce it.

I have about the same specs as yours (except for a i5 CPU) and everything works as intended.

Are you sure your graphic card drivers are up to date, that you're using Firefox's latest version (22) and the webGL is enabled ?

It is Firefox 22, just installed.

I just did a new version printing , dt is almost permanently at 0.1, way too high.

It seems a performance issue in my Firefox. Clean reinstall didn?t solve it. All plugins disable didn?t solve it. Whatever it is, affects just Firefox. It didn?t happened before v22.

However... Shouldn?t plataform work even with a high dt?

In my monitor, it seems to me that the Plataform (Red square) simply jumps past the solids (blue squares), probably because of large dt making large steps.

I am going to work, will check video drivers later.

After a fresh install of Firefox and a new video driver, dt is now between 0.1 and 0.2 and thing run smoothly.

Thank you for you attention.

I think this bug is "closed", if it was ever a bug.
