Max steering angle

[Hasan_R]

@TasKall

Hi there,

I have a pawn blueprint with a chaos vehicle component. I would like to control the front wheel steering angle by changing another parameter. But while i am using the Set steering input node the angle i get is default and controlled (as far as i understand) by the max steer angle from the wheel blueprint) and thus i cannot control the value by using that node.
I tried to use the set wheel max steer angle that support an input for angle in degrees, but then there is no change on the wheel whatever the value will be.

How can I control the front wheel steering angle in a blueprint and add a specific value at will (I have a n input that will update that parameter)
Vehicle blueprint part for steering wheel control

To control the front wheel steering angle dynamically in a Chaos Vehicle Blueprint in Unreal Engine, you can use the “Set Wheel Steering Angle” function. If you are experiencing issues with this function not updating the steering angle as expected, there might be a few things to check:

1.)Ensure the Wheel Is Front Wheel:

Make sure you are applying the steering angle change to the correct wheel. You should only modify the front wheels for steering. Ensure that you are targeting the front wheel in your script.

2. Check If Steering Angle Is Clamped:

Verify if there are any clamping mechanisms or constraints in your vehicle setup that might be limiting the steering angle. Adjust the clamping values if needed.

3. Debugging with Print Strings:

Insert print strings or print debug values to check if the input value you are providing is reaching the “Set Wheel Steering Angle” node and if there are any unexpected values or conditions.

4. Dynamic Steering Input:

If you want to dynamically change the steering angle based on an input, you should use “Set Steering Input” to modify the steering input, rather than directly setting the wheel’s max steer angle. The vehicle will then respond to this input by adjusting the wheel angle accordingly.

Example Blueprint Logic:

blueprintCopy code

// Assuming MySteeringInput is a variable representing your input value (e.g., float)
// This could be controlled by user input, another script, etc.

Event Tick:
Set Steering Input: MySteeringInput // Set your desired steering input dynamically

// OR

Event MyCustomEvent:
Set Steering Input: MySteeringInput // Set your desired steering input when triggered

5. Steering Limitations:

Ensure that there are no conflicting inputs or automatic adjustments happening elsewhere in your vehicle blueprint that might override the manual changes you’re trying to make.

6. Blueprint Graph Order:

Check the order of execution in your blueprint graph. Ensure that the “Set Wheel Steering Angle” node is called at the right time during the blueprint execution.

7. Simulate Physics Flag:

Ensure that the “Simulate Physics” flag is enabled for the wheels or the entire vehicle component. Without physics simulation, steering adjustments may not have any effect.

By carefully examining these aspects and debugging your blueprint, you should be able to dynamically control the front wheel steering angle in your Chaos Vehicle Blueprint in Unreal Engine.
