    <p>I'm working on collision for walls in my game and the way I currently have it I get stuck walking into a wall. I'm trying to make my character slide on the walls but still collide.</p> <p>My character moves off of a vector I create using the angle he is facing.</p> <p>this is my collision function:</p> <pre><code> private static bool CheckForCollisions(ref Crate c1, ref Player c2,bool direction) { for (int i = 0; i &lt; c1.model.Meshes.Count; i++) { // Check whether the bounding boxes of the two cubes intersect. BoundingSphere c1BoundingSphere = c1.model.Meshes[i].BoundingSphere; c1BoundingSphere.Center += c1.position + new Vector3(2, 0, 2); c1BoundingSphere.Radius = c1BoundingSphere.Radius / 1.5f; for (int j = 0; j &lt; c2.model.Meshes.Count; j++) { BoundingSphere c2BoundingSphere = c2.model.Meshes[j].BoundingSphere; if (direction) c2BoundingSphere.Center += c2.position + new Vector3(c2.getPlannedDirection().X, 0, 0); else if (!direction) c2BoundingSphere.Center += c2.position + new Vector3(0, 0, c2.getPlannedDirection().Y); //c2BoundingSphere.Center += c2.position; if (c1BoundingSphere.Intersects(c2BoundingSphere)) { return true; } } } return false; } </code></pre> <p>This is my update:</p> <pre><code>for (int x = 0; x &lt;= 29; x++) { for (int y = 0; y &lt;= 29; y++) { if (crate[x, y].getType() == 11 &amp;&amp; collisionEnabled) { if (CheckForCollisions(ref crate[x, y], ref player,true)) { player.clearPlannedDirectionX(); //Console.Write(player.getPosition().X + "," + player.getPosition().Y + "," + player.getPosition().Z); //movePlayer = false; } if (CheckForCollisions(ref crate[x, y], ref player,false)) { player.clearPlannedDirectionZ(); //Console.Write(player.getPosition().X + "," + player.getPosition().Y + "," + player.getPosition().Z); //movePlayer = false; } } } } </code></pre>

    1. COyou're using getPlannedDirection().X and getPlannedDirection().Y in the first code but you're using clearPlannedDirectionX() and clearPlannedDirectionZ() in the second

    2. COYeah what it was doing was if it would collide on the z axis then it stops it from happening. same with the x axis. this is all run before the player updates its position. that's why its called "PlannedDirection", sorry i should have clarified that in my question.

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.
