This is only a small selection of questions. There are far more topics treated already.
Be sure to SEARCH the forum.
Be sure to search your keyword on the C2 general section as well as this "How do I" section !
The answer you are looking for is probably already out there.

This list is in no way exhaustive and will keep evolving with C2. Nevertheless, it is quite a hard job to compile such a list and especially the phrasing of the questions. I noticed it is often a matter of wording, with people using different terms to speak about the same thing (especially true with GM users arriving with their specific GM "vocabulary" where C2's window is named viewport, and such...)
In the end, the idea is to try to abstract as much as possible to cover the most ground possible.
So, if you noticed a question that has its answer in the forum (in the whole Construct2 forum, "How do I" as well as "General C2 discussions") and you feel like it should be part of the list please post using the following format:
[quote:2dsdlqc5]
Category: A general category where sorting the question.
Sub Category (optionnal): For example if the question is plugin related, this is the name of the plugin.
Question: Keeping in mind this is the "How do I..." section, the question should be clear and the most direct possible.
Link to the answer: You can either post the url of the topic (general URL in the adress bar of your browser) or the specific post URL (to quote a specific post find its link on top left of the post, right click on the image (
) next to the date of the post and select "Copy link").
When the question is covered in several posts in a related topic, post the url of the topic. When the question is covered in a specific post, and/or is not posted in a directly related topic, post the url of the post.
If you encounter an error or a dead link, please post it in this topic. It will be corrected as soon as possible.
This topic is not the place to ask questions. To ask questions, make sure they are not already answered by a search and then, after reading the tips for posting in the "How do I" forum post a new topic.
Any question in this topic will purely be deleted.
This is the only warning.
Also, if you see a question here, please ignore it as it will eventualy get deleted.
Help us keeping this list as up to date, complete and clean as possible.
