calc_eval_number

calc_eval_number #

This entity calculates a result of binary operation on two LR parameters.

The calc_eval_number entity can be used as one of operands for another calc_eval_number entity, allowing to do complex calculations involving more than two operands.

Parameters #

Most parameters are self-descriptive and desribed in fgd.

  • First Operand [LR] - first (left) operand. Can be another entity (including another calc_eval_number) or a literal value.
  • Second Operand [LR] - second (right) operand. Can be another entity (including another calc_eval_number) or a literal value.
  • Third Operand [LR] (optional). After calculating the result of operation on the first 2 operands, make the same operation with the result and the third operand. This allows, for example, to add 3 values or find the maximum among 3 values without resorting to the use of another calc_eval_number.
  • Operation - operation type.
  • Store result in - when calc_eval_number is triggered and the result is evaluated without errors, store the numeric result in other entity like game_number or game_counter.
  • Trigger after operation - when calc_eval_number is triggered and the result is evaluated without errors, trigger this target.
  • Trigger on calculation fail - when calc_eval_number is triggered and the operation failed, trigger this target. The operation may fail if one of the operands couldn’t be calculated due to the source entity being missing or due invalid operation like dividing by zero.

Calc Ratio #

Reports the result of operation. Requesting the result doesn’t fire the targets.

calc_eval_number must not calculate the value from itself directly on indirectly. Otherwise it will lead to the recursion.
