why is this happening, player motion related issue?

| I have made a first person player control using the cubewater.bb example, in my program I have loaded the wall model as shown in Figure below., when the player reaches the wall and looks down, then the upper part of the wall gets cutted as shown in the figure below. The code I am using is written below. What I do to correct that issue ? 1   
Global mvx#,mvz#
Graphics3D 800,600
type_ground=1
type_character=2
type_scenery=3
SetBuffer BackBuffer()
player=CreatePivot()
EntityType player,type_character
PositionEntity player,0,4,0
EntityRadius player,1.5,0.5
camera=CreateCamera(player)
PositionEntity camera,0,1,0
pl=CreatePlane()
PositionEntity pl,0,-1,0
pl_tex=LoadTexture( "E:\textures\marble.jpg" )
ScaleTexture pl_tex,5,5
EntityTexture pl,pl_tex
EntityType pl,type_ground
wall=LoadMesh("E:\wings3d\test_wall.3ds")
PositionMesh wall,0,-1,20
EntityType wall,type_scenery
Collisions type_character,type_ground,2,2
Collisions type_character,type_scenery,2,2
HidePointer()
While Not KeyHit( 1 )
TranslateEntity player,0,-.2,0
mxspd#=MouseXSpeed()*0.25
myspd#=MouseYSpeed()*0.25
MoveMouse GraphicsWidth()/2,GraphicsHeight()/2
campitch=campitch+myspd
If campitch<-75 Then campitch=-75
If campitch>75 Then campitch=75
RotateEntity player,campitch,EntityYaw(player)-mxspd,0
If KeyDown(203) Then mvx=mvx-.02
If KeyDown(205) Then mvx=mvx+.02
If KeyDown(200) Then mvz=mvz+.02
If KeyDown(208) Then mvz=mvz-.02
mvx=mvx/1.2
mvy=mvy/1.2
mvz=mvz/1.2
MoveEntity player,mvx,0,mvz
UpdateWorld
RenderWorld
Flip
Wend
End

| Try tweaking your player entity radius since your camera is parented to it or maybe change the entity radius of camera EntityRadius player,1.5,0.5 |
| ||
| I don't want to increase the entity radius of the player, if I increase the player entity radius then the player is unable to go between the walls, the way between the walls is 3 units wide and 6 units of height. This problem does not not occur when I change the entityradius player, 2.5, 0.5. If I apply this,then I need to make huge size model's, it disrupts the height and width ratios of my model. |
| ||
| yes as I have said lastly change the camera entity radius.. |
| ||
| Try to decrease the min value of the CameraRange, for example : CameraRange(Camera,0.1,100) |
| ||
| Avoid making the near value any lower than you have to though. The resolution of the depth buffer apparently increases dramatically the nearer things are rendered relative to the camera. I forget the specifics of it, but basically try to tweak the near value to remove the clipping issue without making the value too low. |

| @Remid I have fixed the camerarange camera,0.1,1000 it works when Entityradius player, 1.2,0.5 Positionentity camera, 0,1,0 As the camera is only 1 unit above the ground, when I position the camera to a higher position to Positionentity camera, 0,2,0 the problem again occurs, now what I need to fix it. |
| ||
| Your "character controller" may be buggy, you need to forbid the camera to go too near the faces of a mesh, with a camerarange with a minimum value of 0.1, the camera must always be at a distance greater than 0.1 from the faces . |
