    <p>So I'm working on a space game called Star Commander.</p> <p>The progress was going beautifully until I decided I needed to implement some sort of physics. I'm mainly going to be needing Farseer Physics for collision detection.</p> <p>Anyway, since it's a space game, when I am declaring my 'World' object:</p> <pre><code>private World world; this.world = new World(Vector2.Zero); </code></pre> <p>I have no gravity. This causes a weird result. I can collide with objects, but once I stop colliding with them, that's it. I can no longer collide with them and will just go straight through them. However, with gravity:</p> <pre><code>private World world; this.world = new World(new Vector2(0F, 1F)); </code></pre> <p>Collision works beautifully.</p> <p>I've tried looking around for help with Farseer, but a lot of the posts are dated and there are no real good sources for information and sadly, I'm pretty sure I'm not going to get the help I need here either.</p> <p>The only thing I found whilst looking around was that with objects called "Geoms" I need to disable a property called "CollisionResponeEnabled" or something similar.</p> <p>However the Geom object is no longer present in Farseer Physics 3 and has been totally replaced by Fixtures. Fixtures do not seem to have this property, however.</p> <p>I can provide any source code that may help, but keep in mind I am still implementing the physics engine into my project and a lot of the code isn't final and kind of messy.</p> <p><strong>IMPORTANT EDIT:</strong></p> <p>After recording a short gif to demonstrate my issue, I found out that I can only collide with an object once, to collide with it again, I have to collide with a different object, but then cannot collide with that object until I collide with a different object.</p> <p>Example:</p> <p><img src="https://i.imgur.com/DCzVqJr.gif" alt=""></p>

    1. COIt seems to me that your bodies might be "sleeping" after the collision. Have you tried setting `SleepingAllowed = false` on the bodies to see if this is the problem?

    2. COThank you so much. ananthonline I set my player's body to SleepAllowed = false and it worked flawlessly. I appreciate your help greatly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
