OnReachedBottom: Fired when Platform reaches the bottom.

OnBlocked: Fired when Platform is blocked for movement.

Fracturable

Can this object be fractured.

Objects will always be broken in it's Y-axis direction. The Scale in the Y-axis should less than 10.

When an object break, it would remains on other objects it is connected to.

Max Durability: Damage required until glass cracks/non-glass breaks apart.

Should Respawn: Should this fracturable respawn.

Respawn Time: Time before the fracturable will respawn.

Fracture Flags: Reset to default value.

Logic

Logic object is a series of functional capabilities. They receive input from other objects, process it, and output it to other objects.

Branch

Tests a boolean value and fires an output based on whether the value is true (one) or false (zero). Use this entity to branch between two potential sets of events.

Error creating thumbnail: Unable to save thumbnail to destination

Target Name:

The target name that other entities refer to this entity by.

Key values:

Initial value: Initial value of the branch. If you were to call "Test" input now, it would fire either OnTrue or OnFalse depending on this value.

Inputs:

SetValue: Set the boolean value without performing the comparison. Use this to hold a value for a future test.

SetValueTest: Set the boolean value and test it, firing OnTrue or OnFalse based on the new value.

Toggle: Toggle the boolean value between true and false.

ToggleTest: Toggle the boolean value and tests it, firing OnTrue or OnFalse based on the new value.

Test: Test the input value and fire OnTrue or OnFalse based on the value.

Outputs:

OnTrue: This Output fires when the stored boolean value is true (1) and the Test input is fired or when the stored boolean value is set to true (1) by either the SetValueTest or ToggleTest inputs with parameter value 1.

OnFalse: This Output fires when the stored boolean value is false (0) and the Test input is fired or when the stored boolean value is set to false (0) by either the SetValueTest or ToggleTest inputs with parameter value 0.

Compare

It examines the relationship between two numbers ("value" and "compare value"), and fires appropriate output(s).

Error creating thumbnail: Unable to save thumbnail to destination

Target Name:

The target name that other entities refer to this entity by.

Start Disabled:

Start in Disabled State.

Compare Value:

The value to compare against.

Initial Value:

Initial value for the input value.

Inputs:

SetValue: Set the value that will be compared against the compare value. SetValueCompare: Set the value that will be compared against the compare value and performs the comparison. SetCompareValue: Set the compare value. Compare: Force a compare of the input value with the compare value.

Outputs:

OnLessThan: Fired when the input value is less than the compare value. Sends the input value as data.

OnEqualTo: Fired when the input value is equal to the compare value. Sends the input value as data.

OnNotEqualTo: Fired when the input value is different from the compare value. Sends the input value as data.

OnGreaterThan: Fired when the input value is greater than the compare value. Sends the input value as data.

Math Counter

It stores and manipulates a numerical value. It can trigger on reaching user-defined maximum or minimum values, or output its value every time it changes. It also has the ability to perform simple mathematical functions. When the math_counter is disabled, it will become read-only until re-enabled.

Error creating thumbnail: Unable to save thumbnail to destination

Target Name:

The target name that other entities refer to this entity by.

Start Disabled:

Start in Disabled State.

Key Values：

Starting Value: Set the initial value at run-time using the entity's SetValue input. For example, from a logic_relay using its OnSpawn output.

Minimum Value: Minimum legal value for the counter. If min=0 and max=0, no clamping is performed.

Maximum Value: Maximum legal value for the counter. If min=0 and max=0, no clamping is performed.

Clamp Min: Enable Clamping to the Minimum Value.

Clamp Max: Enable Clamping to the Maximum Value.

Outputs:

OnChange: Fired when the counter value changes.If the Target Input's parameters is left empty, the math_counter's value is used.

OnHitMin: Fired when the counter value meets or goes below the min value. The counter must go back above the min value before the output will fire again.

OnHitMax: Fired when the counter value meets or exceeds the max value. The counter must go below the max value before the output will fire again.

Multi Compare

Compares a set of inputs to each other. If they are all the same, fires an OnEqual output. If any are different, fires the OnNotEqual output.

This entity has an internal list of integers that it has received from any inputValue input's. Any values sent to this entity, must be sent as an integer or boolean because "if it can't be converted" the entity will "just throw it away" (Source Code comment from dev's). Currently, there is no way to clear this 'list', so the entity is not reusable.

Target Name:

The target name that other entities refer to this entity by.

Key Values:

Integer Value (optional): Initial integer value.

Should use Integer Value: If set, compare inputs against Integer Value.

Outputs:

OnEqual: Fires if the values are equal (!activator is the activator)

OnNotEqual: Fires if the values are not equal (!activator is the activator)

Random Outputs
