[CLEO] camera angle visibility?

[nyolc8]

Hi all, I'm wondering how to make a particle/corona/anything being drawn only if the camera view is between some angles.

 

So for example, I want to make a corona which is only visible when I look it from north. Is this possible with CLEO?

 

I only found these opcodes which could be useful, but no angle found:

 

 

068D: get_camera_position_to $TEMPVAR_FLOAT_1 $TEMPVAR_FLOAT_2 $TEMPVAR_FLOAT_3068E: get_camera_target_point_to $TEMPVAR_FLOAT_1 $TEMPVAR_FLOAT_2 $TEMPVAR_FLOAT_3

Anyone knows how to make this? Edited February 24, 2015 by nyolc8

script below puts the health object always where the camera is viewing

{$CLEO .cs}:Camera_extended_xy_coordsthread 'CAMEXY'029B: 31@ = init_object 1240 at 0.0 100.0 950.0while truewait 0    if        0256:   player $PLAYER_CHAR defined    then        068E: get_camera_target_point_to 1@ 2@ 3@         068D: get_camera_position_to 7@ 8@ 9@         0087: 5@ = 7@ // (float)         0087: 6@ = 8@ // (float)         0063: 5@ -= 1@ // (float)         0063: 6@ -= 2@ // (float)         5@ *= -5.0         6@ *= -5.0         005B: 7@ += 5@ // (float)         005B: 8@ += 6@ // (float)         01BC: put_object 31@ at 7@ 8@ 3@         0655: AS_actor $PLAYER_ACTOR look_at_object 31@ 1000 ms     endend

position of 068E: get_camera_target_point is between camera_position and player while default camera mode (very near to cam position)
it needs to multiplicate the difference with negativ value to extend the offset to the view direction, to get a sensefull effect

.

Script below turns Player Z-angle always to camera view by using 0604: get_Z_angle_for_point

{$CLEO .cs}:Camera_extended_Anglethread 'CAMEXA'while truewait 0    if        0256:   player $PLAYER_CHAR defined    then        068E: get_camera_target_point_to 1@ 2@ 3@         068D: get_camera_position_to 7@ 8@ 9@         0087: 5@ = 7@ // (float)         0087: 6@ = 8@ // (float)         0063: 5@ -= 1@ // (float)         0063: 6@ -= 2@ // (float)         5@ *= -5.0         6@ *= -5.0         005B: 7@ += 5@ // (float)         005B: 8@ += 6@ // (float)        0063: 7@ -= 1@ // (float)         0063: 8@ -= 2@ // (float)                 0604: get_Z_angle_for_point 7@ 8@ store_to 30@         0173: set_actor $PLAYER_ACTOR Z_angle_to 30@    endend

Thank you, I'll play with these for experimenting

[nyolc8]

I tried to modify the 2nd script and make it to return true (displays "draw" text in the test) only when I look the car from rear (between speicifc angles). Well it works but it's very inaccurate.

Any help to make it accurate? Also it becomes true even when I view the car from front.

works nicely, thank you
