<code>DoMoveAllowed</code> will be used when user will move in the scene, i.e. when user will want to change <a class="normal" href="CastleCameras.TWalkCamera.html#Position">Position</a>.</p>
<p>
<p>ProposedNewPos is the position where the user wants to move (current user position is always stored in Position, so you can calculate move direction by ProposedNewPos - Position).
<p>This is the place to "plug in" your collision detection into camera.
<p>Returns false if no move is allowed. Otherwise returns true and sets NewPos to the position where user should be moved. E.g. if you're doing a simple test for collisions (with yes/no results), you will always want to set NewPos to ProposedNewPos when returning true. But you can also do more sophisticated calculations and sometimes not allow user to move to ProposedNewPos, but allow him to move instead to some other close position. E.g. look what's happening in quake (or just any first-person 3d game) when you're trying to walk "into the wall" at angle like 30 degrees: you're blocked, i.e. you obviously can't walk into the wall, but your position changes a bit and you're slowly moving alongside the wall. That's how you can use NewPos: you can return true and set NewPos to something that is not exactly ProposedNewPos (but is close to ProposedNewPos).
<p>Note that it's allowed to modify NewPos when returning false. This is meaningless, but may be comfortable for implementor of <code>DoMoveAllowed</code>.
<p>BecauseOfGravity says whether this move is caused by gravity dragging the camera down. Can happen only if <a class="normal" href="CastleCameras.TWalkCamera.html#Gravity">Gravity</a> is <code>True</code>. You can use BecauseOfGravity to control <code>DoMoveAllowed</code> behavior — e.g. view3dscene will not allow camera to move lower that some minimal plane when BecauseOfGravity (because this would mean that camera falls down infinitely), on the other hand when BecauseOfGravity is <code>False</code> moving outside bounding box is allowed (to allow camera to look at the scene from "the outside").
<p>Basic implementation of <code>DoMoveAllowed</code> in this class: If <a class="normal" href="CastleCameras.TWalkCamera.html#OnMoveAllowed">OnMoveAllowed</a> = nil then returns true and sets NewPos to ProposedNewPos (so move is always allowed). Else calls <a class="normal" href="CastleCameras.TWalkCamera.html#OnMoveAllowed">OnMoveAllowed</a>.</p>

This procedure corrects <a class="normal" href="CastleCameras.TWalkCamera.html#PreferredHeight">PreferredHeight</a> based on your Radius and on current <a class="normal" href="CastleCameras.TWalkCamera.html#HeadBobbing">HeadBobbing</a>.
<p>Exactly what and why is done: if you do any kind of collision detection with some Radius, then you should make sure that <a class="normal" href="CastleCameras.TWalkCamera.html#RealPreferredHeight">RealPreferredHeight</a> is always >= of your Radius, otherwise strange effects may happen when crouching or when head bobbing forces camera to go down.
<p>Exactly, the required equation is </p>
<pre class="preformatted">
MinimumRealPreferredHeight :=
PreferredHeight * CrouchHeight * (1 - HeadBobbing);

<p> and always must be </p>
<pre class="preformatted">

<p>
<p>Reasoning: otherwise this class would "want camera to fall down" (because we will always be higher than <a class="normal" href="CastleCameras.TWalkCamera.html#RealPreferredHeight">RealPreferredHeight</a>) but your <a class="normal" href="CastleCameras.TWalkCamera.html#OnMoveAllowed">OnMoveAllowed</a> would not allow it (because Radius would not allow it). Note that this class doesn't keep value of your Radius, because collision detection is (by design) never done by this class — it's always delegated to <a class="normal" href="CastleCameras.TWalkCamera.html#OnHeight">OnHeight</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#OnMoveAllowed">OnMoveAllowed</a>. Also, it's not exactly forced <i>how</i> you should force this condition to hold. Sometimes the good solution is to adjust Radius, not to adjust <a class="normal" href="CastleCameras.TWalkCamera.html#PreferredHeight">PreferredHeight</a>.
<p>Anyway, this method will make sure that this condition holds by eventually adjusting (making larger) <a class="normal" href="CastleCameras.TWalkCamera.html#PreferredHeight">PreferredHeight</a>. Note that for Radius = 0.0 this will always leave <a class="normal" href="CastleCameras.TWalkCamera.html#PreferredHeight">PreferredHeight</a> as it is.</p>

If Falling, then this will force Falling to false <b>without calling OnFallenDown</b>. It's much like forcing the opinion that "camera is not falling down right now".
<p>Of course, if in the nearest Update we will find out (using <a class="normal" href="CastleCameras.TWalkCamera.html#OnHeight">OnHeight</a>) that camera is too high above the ground, then we will start falling down again, setting Falling back to true. (but then we will start falling down from the beginning, starting at given <a class="normal" href="CastleCameras.TWalkCamera.html#Position">Position</a> and with initial falling down speed).
<p>This is useful to call if you just changed <a class="normal" href="CastleCameras.TWalkCamera.html#Position">Position</a> because e.g. the player teleported somewhere (or e.g. game levels changed).

<p>With <code>PreferGravityUpForRotations</code>, this affects rotations: horizontal rotations (<a class="normal" href="CastleCameras.TWalkCamera.html#Input_LeftRot">Input_LeftRot</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Input_RightRot">Input_RightRot</a>) and rotations caused by <a class="normal" href="CastleCameras.TWalkCamera.html#MouseLook">MouseLook</a>.

<p>Note that you can change it freely at runtime, and when you set <code>PreferGravityUpForRotations</code> from <code>False</code> to <code>True</code> then in nearest Update calls <a class="normal" href="CastleCameras.TWalkCamera.html#Up">Up</a> will be gradually fixed, so that <a class="normal" href="CastleCameras.TWalkCamera.html#Direction">Direction</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Up">Up</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a> are on the same plane.

<p>With <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a>, this affects moving: horizontal moving (forward, backward, strafe), and vertical moving (<a class="normal" href="CastleCameras.TWalkCamera.html#Input_Jump">Input_Jump</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Input_Crouch">Input_Crouch</a> when <a class="normal" href="CastleCameras.TWalkCamera.html#Gravity">Gravity</a> is <code>False</code>). E.g. when <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a> then forward/backward keys are tied to horizontal plane defined by <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>.

Which is usually more handy when e.g. simulating flying.
<p>It's a delicate decision how to set them, because generally all the decisions are "somewhat correct" — they just sometimes "feel incorrect" for player.
<p></p>
<ul class="paragraph_spacing">
<li><p> First of all, if the scene is not "naturally oriented" around <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>, then you <b>may</b> set <code>PreferGravityUpForRotations</code> as <code>False</code> and you <b>should</b> leave <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Gravity">Gravity</a> to <code>False</code>.
<p>By the scene "naturally oriented around <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>" I mean that we have some proper <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>, not just some guessed <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a> that may be incorrect. For example when view3dscene loads a VRML model without any camera definition then it assumes that "up vector" is (0, 1, 0), because this is more-or-less VRML standard suggested by VRML spec. But this may be very inappopriate, for example the scene may be actually oriented with (0, 0, 1) up vector in mind.
<p>Other examples of the scenes without any "naturally oriented around <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>" may be some "outer space" scene without any gravity.</p></li>
<li><p> With <code>PreferGravityUpForRotations</code> the "feeling" of <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a> is stronger for user, because <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a>, <a class="normal" href="CastleCameras.TWalkCamera.html#Up">Up</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Direction">Direction</a> always define the same plane in 3D space (i.e. along with the 4th point, (0, 0, 0), for camera eye). Raising/bowing the head doesn't break this assumption.
<p>Without <code>PreferGravityUpForRotations</code>, we quickly start to do rotations in an awkward way — once you do some vertical rotation, you changed <a class="normal" href="CastleCameras.TWalkCamera.html#Up">Up</a>, and next horizontal rotation will be done versus new <a class="normal" href="CastleCameras.TWalkCamera.html#Up">Up</a>.
<p>If your <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a> is good, then you generally should leave <code>PreferGravityUpForRotations</code> to <code>True</code>. Unless you really <b>want</b> the player to feel movements as "awkward", e.g. when you want to simulate this "outer space without any gravity" feeling.</p></li>
<li><p> If your <a class="normal" href="CastleCameras.TWalkCamera.html#GravityUp">GravityUp</a> is good, then you generally should set <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a> just like Gravity.
<p>E.g. when the player is flying / swimming etc. he will probably prefer <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a> = <code>False</code>, because this way he will not have to press <a class="normal" href="CastleCameras.TWalkCamera.html#Input_Jump">Input_Jump</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Input_Crouch">Input_Crouch</a>. Simply pressing <a class="normal" href="CastleCameras.TWalkCamera.html#Input_Forward">Input_Forward</a> and <a class="normal" href="CastleCameras.TWalkCamera.html#Input_Backward">Input_Backward</a> and doing rotations will be enough to move freely in 3D space.
<p>When gravity works, <a class="normal" href="CastleCameras.TWalkCamera.html#PreferGravityUpForMoving">PreferGravityUpForMoving</a> = <code>True</code> is better, otherwise player would unnecessarily try to jump when looking up.</p></li>

<p>This is reliable to prevent user from climbing stairs and such, when vertical walls are really vertical (not just steep-almost-vertical).
<p>It's not 100% reliable to prevent player from climbing steep hills. That's because, depending on how often an event processing occurs, you actually climb using less or more steps.
